Our History


The Tandem Family of Companies story. Bruce Leon began his entrepreneurial adventure when he incorporated his insurance agency, Benefits Solutions Group, in 1988. Having been in the industry for a few decades, Bruce began to see a pattern of needs among his small and mid-sized client companies. Beyond great medical, dental and vision insurance premiums, these companies needed assistance with all aspects of human resources. They wanted to create a benefits-rich ‘best place to work’ utilizing a full-service HR team, but did not have the means or needs to hire them in-house.

In 1998, Bruce created a professional HR services solution, Tandem Professional Employer Services (who in 2006 officially changed its name to Tandem HR) to help attract, develop, and retain a great workforce so his clients could compete with larger competitors. Starting with three employees and a handful of clients, Tandem HR has grown to a staff of over 100 servicing over 9,000 client employees. Tandem HR is proud to have been named one of Chicago’s Best Places to Work and Chicago’s Best Places to Work for Women. It has also been recognized as one of Chicago’s Largest Privately Held Companies, Chicago’s Fastest Fifty Growing Companies and made the Inc. 5000 list.

In 2006, Alliance Workplace Solutions joined the quickly growing Tandem Family of Companies to offer voluntary benefits to companies who wanted to supplement their benefits packages with employee purchased and owned policies, such as life insurance, cancer insurance or short or long-term disability.

In 2012, Workplace Solutions Employee Assistance Program (EAP), with approximately 90,000 client employees, completed the Tandem Family of Companies as it is now. Tandem HR is now able to smoothly integrate EAP support into ongoing HR services to provide our clients with additional resources.

With these four companies servicing specific areas of human resources, they are able to provide a custom full-service and one-stop shop for many businesses. The Tandem Family of Companies is excited about the opportunities they have been afforded.

“The steady growth of these companies is due to my dedicated staff and loyal customers.” According to Bruce Leon, “80% of new business is attributed to word-of-mouth referrals. A special ‘thank you’ to all of our clients for helping us get to where we are today!”
