Crain’s Detroit Business last week honored its 40 Under 40 honorees, and they include two Kalamazoo College alumni. They are:

• Ed Mamou ’00, 39, who is the owner of the Root and Mabel Gray restaurants, vice president of GFL Environmental Recycling Services Inc., and vice president of Royal Oak Recycling. Mamou earned a degree in mathematics at K and later earned a master’s degree in applied math at the University of California-San Diego; and
• Sean Mann ’03, 37, who is a former lobbyist and policy adviser in Michigan politics. Mann quit his job with Michigan Legislative Consultants in Lansing on Sept. 5 to become the full-time CEO of Detroit City FC, a semi-pro soccer club that could soon turn professional. He earned a bachelor’s degree in physics and history from K and holds a master’s degree in international relations from the University of Bristol.

Crain’s Detroit Business says all of its 40 Under 40 honorees are professionals who have made “big decisions and bold moves.” They’ve also reinvented themselves and their companies across a variety of sectors and challenges involving fields or attributes such as autonomous vehicles, educational attainment, regional transit, home mortgages and health care.

The honorees were selected by the Crain’s Detroit Business editorial team through nominations selected based on their impact and achievements in business. Read more about the honorees and hear in their own words what they think the next 40 years will hold for Michigan.
