• HealthCare Pros Inc · 4.9★ · Nursing agency

If you mean healthcare staffing agencies that serve California hospitals and clinicians, there isn't one objectively “best” agency—the right choice depends heavily on whether you're hiring staff or looking for work, and on the specialty.

Strong California options

• Host Healthcare — San Diego-based; particularly focused on travel nursing, allied health, and therapy. A good option to investigate for travel assignments.
• Stability Healthcare — Pasadena-based, with travel, local contracts, per-diem, and permanent placement services. It also offers managed staffing services for facilities.
• Epic Travel Staffing — El Segundo-based, with an emphasis on travel nurses and allied professionals, including higher-acuity and hard-to-fill hospital roles.
• FlexCare — Roseville-based travel staffing firm serving nurses, allied-health professionals, and therapists. FlexCare was among the larger U.S. healthcare staffing firms in SIA's 2024 industry data.
• Preferred Healthcare Staffing — San Diego-based, with a particularly strong California per-diem/registry presence and allied-health focus.
• Coast Medical Service — Hermosa Beach-based travel nursing and allied-health staffing agency.
• Healthcare Staffing Professionals, Inc. — Reseda-based; offers temporary/contract and direct-hire recruiting across hospitals, public health, behavioral health, long-term care, and other settings.
• HealthCare Pros Inc — Cypress-based, with local, per-diem, travel, and contract staffing.

Large national agencies worth considering

For a hospital or health system that needs large-scale staffing across multiple specialties, the major national firms are also relevant. SIA's industry data identifies companies such as Aya Healthcare, Medical Solutions, AMN Healthcare, Amergis, Cross Country Healthcare, Soliant, and others among the largest U.S. healthcare staffing providers.

California's 2026 Best of Staffing listings also identify agencies receiving client and/or talent awards, including MediQuest Staffing, Medix, OnPoint Healthcare Solutions, ShareSTAFF, The Plus Group, Epic Travel Staffing, and others.

If you're an employer

I'd compare agencies based on:

• Specialty coverage: RN/LVN, allied health, physicians, behavioral health, etc.
• California credentialing: CA licenses, background checks, competency verification.
• Speed to fill: especially important for per-diem and hard-to-fill positions.
• Geographic coverage: statewide versus Southern/Northern California specialization.
• Bill rates and markup: get an apples-to-apples breakdown.
• Guarantee/replacement terms: what happens if a clinician quits or doesn't work out.
• Managed staffing: useful if you need an agency to coordinate a larger contingent workforce.

California's State Auditor has also documented the use of agencies including Aya, Maxim/Amergis, Cross Country, and others for state healthcare staffing, demonstrating that these aren't merely job-board recruiters but established contingent-workforce providers.

If you tell me whether you're a healthcare professional looking for a job or a hospital/healthcare employer looking to hire, I can narrow this to a practical shortlist—including California-specific agencies, specialties, typical staffing models, and current reviews.

Places ChatGPT showed

• Stability Healthcare · 4.9★ · Employment agency
• Healthcare Staffing Professionals, Inc. (HSP) · 4.9★ · Job Centre
• AMP Staffing Network · 5.0★ · Nursing agency
• HealthCare Pros Inc · 4.9★ · Nursing agency
• Premier Nursing Services · 4.9★ · Nursing agency
• Preferred Healthcare Staffing · 4.7★ · Recruitment Agency
• Epic Travel Staffing · 5.0★ · Employment agency
• FlexCare · 2.2★ · Employment agency
• MedCadre · 4.7★ · Nursing agency

If you’re evaluating agencies as a hospital or long-term-care operator, I’d build the shortlist around staffing model rather than a single “best” ranking. California has both large national firms and California-based agencies, and the right fit differs for travel nurses, per-diem coverage, skilled nursing, and high-volume enterprise staffing.

Agencies worth putting on a California shortlist

For a hospital

For large-volume hospital staffing, I'd specifically investigate Aya Healthcare, Stability, Epic, FlexCare, and HSP, while comparing them on:

• ICU/ER/OR/CVICU availability
• California licensing and credentialing turnaround
• Guaranteed fill rates and replacement policies
• Per-diem versus 13-week travel coverage
• MSP/VMS capabilities
• Agency bill rates and markup transparency
• Quality/screening requirements
• Experience with your specific EHR and facility onboarding requirements

Aya, for example, advertises an enterprise workforce platform, MSP services, and staffing across acute-care hospitals and skilled-nursing facilities.

For long-term care / skilled nursing

For SNFs, nursing homes and assisted living, I'd put more emphasis on agencies that explicitly serve post-acute care rather than choosing purely on hospital travel-nurse volume.

HSP, AMP Staffing Network, MedCadre, HealthCare Pros, and Aya are worth investigating. HSP specifically lists long-term care/skilled nursing among its healthcare settings, while AMP advertises long-term care, skilled nursing and assisted living alongside acute-care hospitals.

One important California consideration

Don't compare agencies solely on the hourly bill rate. California's state auditor has documented substantial use of contract clinical staffing at state facilities, including contracts with firms such as Cross Country, Supplemental Health Care and Medical Edge Recruitment. California's Labor Department has also documented concerns from hospital stakeholders about agency pricing and called attention to transparency around how staffing bill rates are divided between clinicians and agencies.

If you're selecting vendors for a facility, a practical RFP shortlist would be 5–7 agencies, mixing 2–3 large national firms with 2–4 California/regional specialists. That lets you compare actual fill rates and bill rates rather than relying on reputation alone.

If you tell me (1) hospital vs. SNF/LTC, (2) Northern vs. Southern California, (3) RN/LVN/CNA/allied, and (4) per-diem vs. travel/contract, I can narrow this to a facility-oriented shortlist and compare bill-rate model, specialties, geographic coverage, credentialing, and vendor-management capabilities.

If you mean California-based or especially strong for California travel-nursing placements, there are several established agencies worth comparing. I wouldn’t treat any one agency as universally “best,” because pay, available contracts, recruiter quality, and benefits can vary by assignment.

Agencies worth comparing

• Aya Healthcare — San Diego-based and one of the largest nurse staffing companies. It offers travel, per-diem, and permanent nursing positions, with a particularly large national job inventory.
• AMN Healthcare — Another major San Diego-based staffing company with extensive hospital relationships and travel-nursing placements. Its scale can be useful for nurses targeting large health systems.
• Host Healthcare — San Diego-based travel staffing agency focused heavily on travel nursing and allied health. It is worth comparing if benefits and recruiter support are priorities.
• Stability Healthcare — Pasadena-based agency specializing in travel and local contract nursing, including ICU, ER, OR, Med-Surg, L&D and PACU.
• Epic Travel Staffing — El Segundo-based agency with an emphasis on travel nurses, including high-acuity, perioperative and critical-care placements.
• Coast Medical Service — Hermosa Beach-based travel nursing agency that also places allied-health clinicians.
• FlexCare — Roseville-based travel staffing company covering nursing, allied health and therapy nationwide.
• Premier Nursing Services — Long Beach-based nursing agency with per-diem and travel opportunities.
• MedCadre — Irvine-based agency offering contract, travel and permanent nursing roles.

A 2026 industry listing also identifies Epic Travel Staffing, Express Employment Professionals, ShareSTAFF, Staff Today and Accountable Healthcare Staffing, among others, as California travel-nursing staffing companies receiving Best of Staffing recognition.

For a California travel nurse, I'd compare these factors

1. Weekly gross package — compare the entire package, not just taxable hourly pay.
2. California licensing support — California is a non-compact state, so licensing/endorsement assistance can matter.
3. Hospital access — ask specifically whether the agency has the California facility you want as a direct/preferred client.
4. Stipends and reimbursements — get housing, meals/incidentals, travel reimbursement, and any one-time payments in writing.
5. Cancellation policy — particularly important for California assignments where housing can be expensive.
6. Benefits — insurance effective date, 401(k), PTO, sick leave, and whether benefits continue between assignments.
7. Recruiter quality — this can make a surprisingly large difference. If possible, talk with the actual recruiter before submitting to a facility.

One useful strategy is to submit the same California assignment through 2–3 agencies and compare the written packages. Independent 2026 comparisons similarly note that no agency consistently offers the highest pay for every assignment.

If you tell me your specialty (ICU, ER, OR, L&D, Med-Surg, etc.), years of experience, and the California area you want (LA, San Diego, Bay Area, Sacramento, etc.), I can narrow this down to agencies that currently have relevant California contracts and compare their pay/benefits.

If by “fill shifts the fastest” you mean same-day, next-day, or high-fill-rate coverage, there isn’t a public, standardized ranking of California healthcare staffing agencies by actual fill speed. Speed depends heavily on specialty (RN vs CNA vs MA vs allied health), location, facility type, pay rate, credential status, and whether the agency already has a local roster.

That said, agencies and platforms that tend to be positioned for rapid per diem / urgent coverage in California include:

That said, agencies and platforms that tend to be positioned for rapid per diem / urgent coverage in California include:

For fastest fill rates, look for these features

Agencies that consistently cover urgent shifts usually have:

For fastest fill rates, look for these features

Agencies that consistently cover urgent shifts usually have:

• Pre-credentialed local clinicians (active CA license, BLS, background checks, health records already cleared)
• Mobile/app shift acceptance
• 24/7 scheduling support
• Large local float pools
• Competitive facility rates
• Specialty-specific recruiters (ICU, ED, behavioral health, SNF, urgent care, etc.)

For example, some California staffing firms advertise per diem response windows around 24–48 hours when credentialed candidates are available, but that is not the same as a guaranteed fill time for every shift.

If you mean as a healthcare facility trying to cover open shifts, the answer differs from as a nurse/CNA trying to pick up shifts. Also, which part of California (Los Angeles, Bay Area, San Diego, Sacramento, Central Valley, etc.) and which roles (RN, LVN, CNA, MA, allied health)?

If by “reliable” you mean established, active in Southern California, broad facility access, and a track record of placing healthcare professionals, there are several agencies worth comparing. I wouldn’t treat any single agency as universally best—the experience can vary substantially by recruiter and specialty.

Strong Southern California options

• Host Healthcare — San Diego-based and particularly focused on travel nursing and allied health. It has a large local review base and nationwide placement capability.
• Stability Healthcare — Pasadena-based, with travel nursing, travel allied, per diem and permanent placement services. Its local business listing has a substantial review volume.
• Coast Medical Service — Hermosa Beach-based, specializing in travel nursing and travel allied health.
• Healthcare Staffing Professionals, Inc. (HSP) — Reseda-based and more diversified, covering clinical and nonclinical healthcare, temporary/contract and direct-hire positions.
• Premier Nursing Services — Long Beach-based, with an emphasis on per-diem nursing and travel-style assignments throughout Southern California.
• Preferred Healthcare Staffing — San Diego-based and particularly relevant for allied-health professionals, as well as California per-diem and travel positions.
• Global Service Resources (GSR) — Burbank-based and operating since 1993, with both clinical and nonclinical healthcare staffing in Southern California.
• HealthCare Pros Inc. — Cypress-based, offering local registry/per-diem, travel and contract opportunities.

Several of these aren't just local boutiques: Los Angeles County and San Bernardino County procurement documents list agencies including Aya, Cross Country, HSP, Maxim/Amergis, HealthCare Pros, NuWest, ProLink, Pioneer, and others as healthcare staffing vendors.

What about Aya, AMN, Cross Country and Maxim/Amergis?

They're also major players to consider. Aya is headquartered in San Diego and has a very large travel-nursing operation. Third-party data shows a large volume of verified reviews, although review sources aren't uniformly positive; for example, BBB currently shows complaints alongside other review platforms showing strong clinician ratings.

A California State Auditor report also documents substantial state healthcare staffing contracts involving Aya, Maxim, Cross Country and Supplemental Health Care, among others.

How I'd narrow it down

The right shortlist depends heavily on what kind of healthcare worker you are:

• RN/LVN: Host, Stability, Aya, Coast, Premier
• Allied health: Preferred, Host, Stability, Coast
• Per-diem/local shifts: Premier, Preferred, HealthCare Pros, Stability
• Nonclinical healthcare / administrative: HSP, GSR, HealthCare Pros
• Travel contracts: Aya, Host, Stability, Coast, Cross Country, AMN

When comparing offers, don't look only at the advertised hourly rate. Compare total weekly compensation, stipends, guaranteed hours, cancellation terms, benefits, insurance start date, overtime rules, travel reimbursement, and the recruiter’s responsiveness.

If you tell me your profession (e.g., RN, LVN, CNA, respiratory therapist, radiology tech, medical assistant, physician) and whether you want per diem, local contract, permanent, or travel, I can narrow this to the most relevant Southern California agencies and compare them side-by-side.

• ALOIS Healthcare · 4.8★ · Job Centre
• CareerStaff Unlimited - San Francisco | Sacramento · 5.0★ · Employment agency
• FlexCare · 2.2★ · Employment agency
• Trusted Health · 4.7★ · Software company
• Star Nursing · 4.3★ · Temp agency
• Power Personnel · 2.8★ · Employment agency
• TheraEx Staffing Services · 4.4★ · Nursing agency
• Triage Staffing · 4.7★ · Employment agency

If you mean healthcare staffing agencies that serve Northern California hospitals, clinics, SNFs, and other healthcare employers, there are several established options. “Best” depends heavily on whether you're hiring RNs, allied health, physicians/APPs, per-diem staff, or permanent employees.

Strong Northern California options

• ALOIS Healthcare — San Francisco. Healthcare staffing with a focus on travel nurses and allied-health professionals, plus local and permanent placements. Its SF presence makes it particularly relevant for Bay Area coverage.
• CareerStaff Unlimited - San Francisco | Sacramento — Pleasanton / SF-Sacramento market. Offers per-diem, contract, travel, and permanent healthcare staffing and broader workforce solutions.
• FlexCare — Roseville. Particularly focused on travel nursing, allied health, and therapy staffing.
• Trusted Health — San Francisco. A tech-enabled staffing platform focused heavily on nursing and allied-health local/travel contracts.
• Star Nursing — Folsom. California-based staffing organization offering travel, per-diem, and permanent/direct-hire staffing.
• Power Personnel — San Jose. A Bay Area-focused healthcare staffing and recruiting firm, useful if your needs are concentrated in Silicon Valley/South Bay.
• TheraEx Staffing Services — Concord. Provides travel, local/per-diem, and crisis staffing, with an emphasis on nursing and allied health.
• Triage Staffing — Mountain View. Travel healthcare staffing for nurses and allied professionals.

Large national agencies worth including

For a hospital or health system that needs scale across multiple Northern California facilities, I'd also put these on the RFP list:

• Aya Healthcare — nursing, allied health, travel, per-diem, permanent, and workforce-management services. Aya says it has more than 1,000 recruitment professionals and serves hospitals, SNFs, imaging centers, practices, surgical centers, and home health.
• AMN Healthcare — particularly broad coverage: nursing, allied health, physicians, APPs, travel, per-diem, temp-to-hire, and permanent placements.
• HealthTrust Workforce Solutions — nursing, allied health, locums, and interim leadership; it has direct access to HCA Healthcare's network.
• Cross Country Healthcare — a major national staffing provider with California contracts; California's State Auditor lists Cross Country among vendors providing licensed/certified clinical staffing to state facilities.

If you're hiring for a facility

I'd build the shortlist differently depending on the role:

One useful objective indicator: California's State Auditor's recent report identifies Cross Country, Supplemental Health Care, Medical Edge Recruitment, and others as vendors with state clinical-staffing contracts, so they're worth considering when experience with California public facilities matters.

If you tell me (1) whether you're an employer or a clinician, (2) the roles you need, and (3) which part of Northern California—Bay Area, Sacramento, North Coast, etc., I can narrow this to a 5–10 agency shortlist and compare fees, specialties, local presence, and reviews.

Places ChatGPT showed

• Epic Travel Staffing · 5.0★ · Employment agency
• Aya Healthcare · 4.7★ · Recruiter
• FlexCare · 5.0★ · Corporate office
• Coast Medical Service · 4.9★ · Employment agency
• Preferred Healthcare Staffing · 4.7★ · Recruitment Agency
• Platinum Healthcare Staffing · 2.3★ · Employment agency

If by “best-credentialed” you mean agencies that appear to have strong clinician screening, licensing/credential verification, specialty matching, and compliance infrastructure—not simply the largest candidate pool—these are the California agencies I’d put on a serious shortlist:

• Epic Travel Staffing — Particularly relevant for high-acuity nurses and allied clinicians. Its staffing model emphasizes critical care, perioperative, oncology and placements with academic/Magnet hospitals.
• Aya Healthcare — Very large credentialed nursing/allied-health pool. Aya reports an average of 8 years' clinician experience, 77%+ with a bachelor's degree or higher, and 95% on-time starts through its credentialing/compliance operation.
• FlexCare — California-based and focused on travel nursing, allied health and therapy; worth considering where specialty matching and credentialed travel clinicians are priorities.
• Coast Medical Service — California-based travel nursing/allied staffing agency that advertises Joint Commission certification, making its compliance infrastructure particularly relevant.
• Preferred Healthcare Staffing — Especially interesting for allied health and California per-diem/registry staffing; it states that it holds Joint Commission's Gold Seal for healthcare staffing services.
• Platinum Healthcare Staffing — Advertises structured verification of licenses, certifications, experience and competency, along with Joint Commission certification.

What I'd actually use to compare them

There isn't a reliable public database that lets us say one agency has the most qualified clinicians. A better objective screen is:

1. Joint Commission HCSS certification — This independently evaluates a staffing company's processes and requires standardized performance measurement.
2. License and primary-source verification — Ask whether licenses are verified directly with the licensing authority rather than relying solely on documents supplied by the clinician.
3. Specialty competency validation — Especially important for ICU, OR, NICU, ED, oncology, behavioral health and other high-acuity roles.
4. Recent clinical experience requirements — Ask for minimum recent hours in the exact specialty/unit.
5. Certifications — BLS/ACLS/PALS/NRP, specialty certifications such as CCRN, CEN, CNOR, etc., as applicable to the position.
6. References and performance history — Ask whether the agency can provide assignment history, competency assessments and facility evaluations.
7. Credentialing turnaround and auditability — You want an auditable credential file rather than simply an assertion that a clinician is “credentialed.”

For context, the California State Auditor's recent review of state healthcare staffing contracts identifies Cross Country Staffing, Supplemental Health Care, Medical Edge Recruitment and other firms as providers of licensed/certified clinical staffing to California state facilities. Cross Country's staffing businesses also have documented Joint Commission certification and credential-verification infrastructure.

If you're a California hospital/health system choosing an agency, tell me the clinician type you're trying to staff (e.g., ICU RNs, CRNAs, physicians, allied health, behavioral health, or home health) and whether you need per diem, travel, locums, or permanent placement. I can then compare the agencies specifically on credentialing rigor, specialty depth, California coverage, and available evidence—without relying on generic “best agency” rankings.

• Healthcare Staffing Professionals, Inc. (HSP) · 4.9★ · Job Centre
• AMP Staffing Network · 5.0★ · Nursing agency

If by “trusted” you mean established, locally/family owned, healthcare-focused, and with evidence of facility relationships, a few California agencies stand out. There isn’t a reliable statewide ranking of “most trusted,” so I’d look at ownership, longevity, facility footprint, credentialing, and independent client/facility evidence rather than ratings alone.

California agencies worth vetting

• Healthcare Staffing Professionals, Inc. (HSP) — Reseda/Los Angeles
• California-based healthcare staffing firm serving hospitals, public-health agencies, SNFs, behavioral health and other healthcare settings.
• Importantly, the California State Auditor's 2025 report shows HSP held a state healthcare staffing contract for RN/LVN/CNA-level staffing with a maximum contract value of about $159.2 million for the 2023–2026 period.
• This is one of the stronger pieces of objective evidence that the company has handled substantial institutional staffing requirements.
• Per Diem Staffing Systems — Concord / Northern California
  *
• Family-owned and operated, in business since 1968, and specifically focused on nursing, respiratory therapy, CNAs and allied healthcare.
• The company says it is Joint Commission certified and serves hospitals and healthcare organizations throughout California.
• For a facility looking for a genuinely long-established California staffing relationship, this is particularly notable.
• Nurses & Professional Healthcare (NPH) — Chico / Northern California
  *
• Locally owned and operated since 1988, according to the company; it says it currently connects healthcare professionals with 130+ facilities.
• Staffs RNs, LVNs, CNAs and respiratory therapists throughout the North State.
• This would be one of my first agencies to investigate if you're a Northern California facility.
• C.E.N.M. Healthcare — Temecula / Southern California
  *
• Nurse-led, family-founded/family-operated, with its California headquarters in Temecula.
• Provides staffing to skilled nursing facilities, hospitals and home-health agencies and emphasizes clinical vetting and 24/7 support.
• It's newer/smaller than Per Diem or NPH, so I'd verify facility references and contract history directly.
• ApexCare Staffing Solutions — Sacramento
  *
• Nurse-owned and California-focused, providing CNA, LVN and RN per-diem, contract and urgent coverage.
• Its leadership describes firsthand clinical/facility experience and California regulatory expertise.
• I'd consider this more of an emerging local agency and conduct additional reference checks before placing a large volume of shifts.
• AMP Staffing Network — Cerritos / Southern California
• California-based nursing agency providing per-diem, contract and direct-placement staffing to healthcare facilities.
• The local-business data shows a 5.0/5 rating, although the review volume is small, so I wouldn't treat that alone as evidence of institutional trust.

One important distinction

There are also locally owned franchises of national staffing brands. For example, describes its California operations as locally owned and operated franchises while benefiting from the national organization's infrastructure.

That can be attractive if a facility wants local ownership + national compliance/resources, but it isn't the same thing as an independent California family-owned agency.

If you're evaluating them as a healthcare facility

I would ask each agency for these six things before signing an MSA:

1. 3 current facility references—preferably facilities similar to yours.
2. Actual fill rate for RN/LVN/CNA shifts in your geographic area.
3. Credentialing checklist—license verification, exclusion checks, background checks, health screens, competencies and references.
4. Joint Commission certification/accreditation, if applicable.
5. Average time to fill routine versus urgent shifts.
6. Proof of insurance and indemnification terms, plus their workers' compensation arrangement.

For objective validation, the California State Auditor's recent report is particularly useful because it documents actual state healthcare-staffing contracts rather than relying on an agency's marketing claims.

If you tell me what type of facility you operate (SNF, hospital, behavioral health, home health, assisted living, correctional, etc.) and the California region (LA/OC, Inland Empire, San Diego, Bay Area, Sacramento, Central Valley, etc.), I can narrow this to 5–10 locally/family-owned agencies that actually staff that type of facility, including ownership, years in business, specialties, accreditation, facility footprint, and available evidence of client trust.
