Aaron Klosterman

President of Grand Pointe Automotive

Aaron has spent 34 years in the automotive industry, turning a lifelong passion for anything mechanical into a career dedicated to automotive repair, leadership, and serving the community.

His interest in vehicles started as a kid, when he would take apart bikes, motorcycles, lawn mowers, and just about anything with nuts and bolts, usually just to see how it worked. Throughout his career, Aaron specialized in electrical and computer diagnostics, heating and A/C systems, and other challenging repairs. Automotive A/C became a favorite, and shops throughout Genesee County would often send him vehicles they couldn’t diagnose.

Today, Aaron’s favorite part of Grand Pointe Automotive is building relationships with customers and developing the team. He takes pride in seeing generations of families continue to trust Grand Pointe and enjoys helping team members grow and reach their career goals.
Aaron currently drives a Ford F-250 Super Duty. His dream vehicles include a Chevy El Camino, first-, second-, and third-generation Ford Broncos, a Ford GT, and a Ford Mustang.

Outside of work, Aaron enjoys traveling, camping, fishing, and spending time with his wife and two kids, including attending his son’s sporting events and his daughter’s dance competitions. The family also has a dog named Maggie although, Aaron says she’s really his wife’s dog!

Aaron is also passionate about giving back to the community that has supported Grand Pointe since 1950, from supporting local fundraisers, schools, police and fire departments to helping families in need.
