Marcus, Owner of GF Tech

I have spent my whole life around cars and boats.  I received my formal education from Washtenaw Community College earning certificates in autobody repair and paint and Custom Cars and Concepts.  While gaining my education, I worked as a teacher’s assistant in the autobody department.  After college, I worked at Transtar Autobody Technologies as a Technical Representative.  My duties included: Product development and testing, creating and implementing training courses for employees and the end-user, complaint investigation and resolution, and software troubleshooting and testing.

After 7 years I left Transtar to restore classic cars for a private owner’s collection and try to become my own boss running an automotive paint distribution & supplier.  Two years later when the business was not growing and the project cars were finished, I went back to work for Ford Motor Company as a clay mill operator in the product development department.  My skills with automotive repair were quickly recognized and I was moved to the composites department where I created parts from scratch with fiberglass and plastics.

After Covid-19 hit, I was laid off from Ford and started working at a custom restoration shop downriver.  During that time I sold my house and moved, had a child, and had the urge to start another business. With the money I earned from selling my house, I started GF Tech.  I recognize the need for quality and reliable work in the marine environment. I have set my sights on becoming the name for boat repair and detailing for Southeast Michigan and Northern Ohio boating community.

 When I am not working I like to spend my time enjoying life with my family.  Boating and swimming take up most of our days in the summer.  I also have taken up mountain biking and plan on exploring the world of sailing.  My parents are members of a boat club and we spend a lot of time there and out on the water whenever we can.  During the winter months, I like to go snowboarding and ice fishing and look forward to taking my son out on these adventures when he is old enough.
