About Tandem HR

Tandem HR, founded in 1998 by Chicago-based benefits consultant Bruce Leon, is the largest privately held PEO in the Midwest and a leading HR solutions provider. What began with the founding of Benefits Solutions Group in 1997 evolved into Tandem Professional Employer Services (PES), which quickly grew through word-of-mouth referrals due to its high-quality outsourced HR services. In 2008, the company rebranded to Tandem HR to better reflect its expanded service offerings. Today, our HR experts provide exceptional human resource solutions that boost shareholder profitability and operational efficiency to clients nationwide. We can support your business with tailored services in areas like employee onboarding, benefits orientations, payroll administration, risk management, employment law compliance, and more.
