Best U.S. staffing agencies to start with

There isn’t one “best” agency for every job. The best choice depends on whether you need office/professional, IT, industrial, education, healthcare, or executive hiring. My short list below balances brand recognition, national reach, specialty depth, and actual market usage.

My top 10 “default” picks

If you just want the brands most people should check first in the U.S., I’d start here:

1. Robert Half — best default for professional/office roles.
2. Allegis Group brands: TEKsystems, Aerotek, Aston Carter — best big-network option by specialty.
3. Randstad USA — broad national staffing.
4. ManpowerGroup / Experis — general temp + IT/professional staffing.
5. Kelly / Kelly Education — education, science, engineering, professional, and temp staffing.
6. Adecco — industrial, admin, warehouse, and volume staffing.
7. Insight Global — IT, engineering, healthcare, finance, project staffing.
8. Express Employment Professionals — local branch-based staffing.
9. Kforce — IT and finance/accounting.
10. Korn Ferry — executive search and senior professional recruiting.

Quick recommendation by situation

• You’re a job seeker in accounting/finance/admin: Start with Robert Half, Aston Carter, Randstad, and Kforce.
• You’re in IT or software/data/cloud: Start with TEKsystems, Insight Global, Kforce, Experis, and Randstad Digital.
• You want warehouse, manufacturing, logistics, or light industrial work: Try Aerotek, Adecco, Randstad, Manpower, Express, and PeopleReady.
• You’re a substitute teacher or school worker: Check Kelly Education first where available.
• You’re a nurse, allied health worker, or physician: Use healthcare specialists like Aya, AMN, CHG, and Jackson Healthcare.
• You’re hiring executives: Use Korn Ferry, Spencer Stuart, Heidrick & Struggles, Russell Reynolds, or Egon Zehnder; Forbes’ 2025 executive recruiting top five included Korn Ferry, Robert Half, Spencer Stuart, Heidrick & Struggles, and Russell Reynolds. (forbes.com)

Practical tip: for most job seekers, register with 2–4 agencies in your specialty, not 20. Agency quality varies heavily by local office and individual recruiter, so the “best” agency is often the one with the strongest local desk for your exact role.

Here's a breakdown of the leading staffing agencies in the U.S., based on market share, industry rankings, and specialty focus.

Big, general-purpose staffing giants

These are the household names most people encounter first when searching for temp or full-time work across industries:

• ManpowerGroup – Forbes' 2026 list of America's best temporary staffing firms ranked Manpower No. 1 and Kelly Services No. 2, based on approximately 13,800 survey responses collected between November 2025 and January 2026 from recruiters, HR leaders, and job seekers.
• Kelly Services – The #2 pick on that same Forbes list, another long-established name for general and light industrial staffing.
• Randstad USA – Frequently cited as best when mass hiring is needed across industries.
• Adecco USA – A major national player; it provides both national coverage and on-the-ground support, which is critical for managing multi-location workforces, with deep experience with complex, multi-state labor compliance and safety protocols, reducing risk for clients.
• Allegis Group (parent of TEKsystems, Aerotek) – leads on sheer size compared to competitors like Robert Half and Insight Global.

By specialty — where the real "best" answers usually live

Staffing is highly niche-driven, so the "best" agency really depends on what you're hiring for:

IT / Tech staffing

• TEKsystems — leads IT with $5.8B in revenue, and is described as best when it comes to large-scale IT and tech staffing.
• Kforce — a strong second choice for organizations that span IT and finance hiring, or where 60+ years of institutional knowledge and a public company compliance posture matter to procurement.
• Beacon Hill Staffing — holds Top 10 status among IT staffing firms in SIA's 2025 ranking, with 60+ offices across all 50 states with 800+ staffing professionals and 5,000 deployed consultants.
• Insight Global and Experis are also commonly listed among top IT-focused firms.

Healthcare staffing

• Aya Healthcare — the market leader, leads healthcare with $6.9B in revenue and a 16% market share. It grew further after Aya Healthcare acquired Cross Country Healthcare for $615 million in late 2024.

Finance & accounting / administrative

• Robert Half — the classic name here, widely cited as ideal in finance, legal, and administrative areas. It's a long-standing brand, a U.S.-based specialty staffing firm founded in 1948.

Industrial / light industrial

• Express Employment Professionals and Aerotek — each hold about 6% of the industrial market.

Executive search

• Korn Ferry and Lucas Group are commonly named among top executive-search firms alongside the generalist players above.
