Back in 2000, when I founded CoStaff to help small businesses enhance their operations and workforce, I was guided by a simple yet fundamental principle: Deliver a level of service I would expect from a human resources partner that puts people first.
What started as a small Michigan-based professional employer organization (PEO) has grown into one of the Midwest’s most trusted HR solutions providers. As CoStaff celebrates its 25th anniversary, that trust is clear — three of our first four clients from 2000 are still with us today. Our latest client satisfaction survey scored us 9.5 out of 10, reinforcing what consistency, transparency and a client-first mission can achieve. In an industry often seen as impersonal or transactional, CoStaff builds something different: people-first HR solutions grounded in partnership and purpose.
Human Resources is About People and Relations
At CoStaff, our success comes from our belief that human resources should put people first, not profit. While other PEOs may bury clients in hidden fees, confusing bundles and impersonal service via 800 numbers and ticket systems, we’re built on a foundation of transparency. Our clients know exactly what they’re paying for and that they’re never alone. We harness the power of good old-fashioned personal engagement to forge honest, lasting relationships. Each client works with a dedicated CoStaff team of real HR professionals who get to know their business and their people inside and out. No chatbots. No artificial intelligence. Just real people solving real problems.
Simplifying Employment for Today’s Workforce
The workplace has changed dramatically in the last two decades. From compliance requirements to competitive benefits and evolving employee expectations, HR is more complex than ever and requires a full-service HR partner that stays ahead of the curve.
That’s why CoStaff delivers innovative solutions that are custom-engineered to your business and your people, so you can focus on doing what you do best:
- From leveraging the latest in payroll processing software to expert risk management and compliance consultation and beyond, our user-friendly tools and personalized services help you save time and money by streamlining your operations and delivering the best employment experience for your team.
- Providing access to the volume purchasing power of our relationships with Fortune 500-level benefits providers — including Blue Cross Blue Shield, UnitedHealthcare, Health Alliance Plan and Priority Health — to attract and keep your employees happy, healthy and engaged for the long haul.
- Understanding the challenges you face, because we’ve faced them as a small startup with a handful of employees, a strong belief in doing things right and a relentless commitment to service. That entrepreneurial spirit is why we are uniquely skilled at managing the administrative complexities of an HR back office.

Over the years, CoStaff has grown because our clients have grown. They’ve invited us into their businesses during pivotal moments — whether scaling up, navigating change or facing uncertainty. Each time, we’ve been there with solutions that not only helped them succeed but also reinforced our partnerships.
HR doesn’t have to be complicated. With the right partner, it can be a powerful engine of financial and cultural growth.
At CoStaff, we believe doing right by people is the best way to do business. When your business is ready for a single-source HR partner that puts transparency, trust and people first, we’re here for you — just like we’ve been for the past 25 years.
