Simplifying employment since 2000 

In 2000, Michael Bulgarelli founded CoStaff Services, which today is one of Michigan’s largest Professional Employer Organizations (PEOs), servicing clients throughout southeast Michigan, across the state and around the country. When Michael started the company, he asked himself, “If I were the client, how would I build the service offering?” and designed CoStaff Services around the answers to that simple question. 

CoStaff has since evolved to servicing hundreds of clients and managing thousands of employees — many of which have been with CoStaff since its inception. Today, our seasoned team of experts and professionals averages 15 years of experience in their respective fields. 

In 2007, CoStaff launched CoStaff Benefit Services, an employee benefit agency servicing its PEO clients, as well as benefits-only clients that work direct to the insurance carriers. This expanded our service offering to now be able to offer employee benefits only.

Our mission is to provide best-in-class services and products, beginning with a state-of-the-art HRIS platform in PrismHR and extending through volume purchasing power that allows our clients to attain Fortune-500 benefits offerings through BlueCross BlueShield, Blue Care Network, Unum, Captrust, Omega Benefit Strategies and other elite institutions. 

We’ve learned that a people strategy makes all the difference. It takes people who are engaged and motivated to get the job done right day after day for a company to thrive and grow. Our proven approach allows companies to mitigate costs and risk by leveraging CoStaff Services’ HR infrastructure to become more efficient and profitable.
