History

In 1997, Tom McGraw and Bill Wentworth launched an independent employee group benefits firm focusing on serving the unique needs of mid-size Michigan employers. Financing the company themselves, Tom and Bill launched McGraw Wentworth with just one employee and no clients, and went without paychecks for the first two years.  With a different business model – focusing only on health care benefits and providing a higher quality client experience – and a passion for our Vision & Principles, McGraw Wentworth succeeded in becoming the region’s largest employee group benefits firm.

Marsh & McLennan Agency LLC (MMA) acquired McGraw Wentworth in December 2012.  In 2014, MMA also acquired Great Lakes Employee Benefit Services.  Combined, Marsh & McLennan Agency | Michigan now has over 90 Health & Benefits employees partnering with over 220 employers including privately-and publicly-held firms, municipalities, school districts, non-profits, manufacturers, services, retailers and wholesale firms. This diverse client base ensures our firm’s stability and growth, while also allowing us to share best practices from each industry.

As a part of MMA, we now have expanded resources and a network of expertise to call upon as needed.  This includes Property & Casualty services, available both locally via our office in Livonia and nationally.

MMA Michigan has been exceptionally attentive and responsive, and have been very proactive in helping us get on track and moving in the right direction. We are very impressed with their expertise. — AMT Services, Inc.
