Top Staffing Agencies in the U.S. (2026)

The "best" staffing agency really depends on what you're hiring for (or what job you're looking for) — general staffing, IT, healthcare, finance, or industrial/light industrial. Here's a breakdown of the brands that dominate each category and are the ones people most commonly actually use:

By Specialty — Segment Leaders

TEKsystems ($5.8B revenue) leads IT, Aya Healthcare ($6.9B, 16% share) leads healthcare, Robert Half tops finance, and Express Employment Professionals and Aerotek each hold about 6% of the industrial market. These are the household names that show up most often across rankings because of scale and consistent placement volume.

IT Staffing

If you need tech talent, the most frequently recommended names are:

• TEKsystems – TEKsystems is the answer for pure volume at enterprise scale.
• Kforce – Kforce is the right 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 – operates 60+ offices across all 50 states with 800+ staffing professionals and 5,000 deployed consultants, and holds a consistent

When asking for the "best" staffing agencies, the answer really depends on what kind of work you’re looking for (corporate office, tech, healthcare, or light industrial) and whether you're looking for a temp/contract gig or a permanent full-time role. That said, here are the top staffing brands that people actually use and trust in the U.S. right now, broken down by specialty.

🏆 Best for General / Clerical & Light Industrial

1. Robert Half
The gold standard for office & finance.
They dominate administrative, accounting, and finance placements. Their "Accountemps" division is huge for temp accounting clerks and analysts. People use them because they have decades of relationships with mid-to-large companies.

2. ManpowerGroup (Manpower)
Massive for blue-collar, warehouse, and industrial roles.
If you’re looking for assembly, logistics, or general labor, this is the go-to. They have a huge nationwide network and often have same-day start gigs.

3. Adecco
Similar to Manpower but with a stronger healthcare and manufacturing tilt.
Great for temp-to-hire roles in factories, distribution centers, and even some entry-level office positions.

💻 Best for Tech, IT & Engineering

4. TEKsystems
The 800-pound gorilla for IT staffing.
If you’re a developer, network engineer, or IT project manager, TEKsystems places thousands of contractors at Fortune 500 companies. They’re not always the highest payers, but they get you in the door.

5. Randstad Technologies
Part of the global Randstad group, but U.S.-specific for tech.
Strong for software engineering, cloud roles, and cybersecurity. Many people use them for contract-to-hire positions at big banks and retailers.

6. Insight Global
Very popular for lower-to-mid level IT roles (help desk, jr. developers).
They have a huge internal training program and often place people with zero experience in IT. However, their pay rates are sometimes lower than specialized firms.

💼 Best for Professional / Executive Roles

7. Lucas Group (recently acquired by Hunt)
Top choice for military-to-civilian transitions and upper-management placements.
Highly respected for placing managers, directors, and VPs in sales
