Beacon Hill Staffing

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.
