Agency Principal

John and Diane Mace

Hello, my name is John Mace and, along with Diane Mace, we are co-owners of the Mace Insurance Agency. I am from the Downriver Community of Southgate and graduated high school from Wyandotte St. Patrick. I attended Eastern Michigan University and taught high school math at Gibraltar Carlson High School from 1969 to 1994. For twenty years of my teaching career and ten years since I retired, I have been a proud Meemic representative. I earned my agent's license in 1975. I started out selling and servicing personal lines insurance from my home in Brownstown and later in my Riverview home. I am now selling insurance out of my office in Downtown Trenton. We are able to take care of your insurance needs, the customer, in a more professional manner.

Being in business for 30 years, we are now writing policies for the children of my original customers. I notice, too, my original customers are retiring and leaving the state for warmer climates. It has been a pleasure to service the educational community in the Downriver area for the last thirty years.

Diane Mace is co-owner of the Mace Insurance Agency. Diane Mace is from the Downriver area growing up in Rockwood. She has been a fully licensed agent with Meemic and serviced our clients since 1984. When we first started the agency, she was the initial contact person in the office while I was teaching full time. You can find her daily in the Trenton office.
