About Us

Our History

The DeMers family has provided automotive repair and service in Longmont and the surrounding areas for over six decades. The current owner, Marvin DeMers, acquired “DeMers Service Center” from his father, Richard, in 1993, and renamed it “DeMers Automotive.” Almost thirty years later, he has continued the family tradition, and now the third-generation has joined the business.

Customer service is paramount at DeMers Automotive, and we have been a NAPA AutoCare Center membership since 1999. This provides nationwide warranty protection for our customers. No matter the location, NAPA will stand by our work anywhere in the USA our customers happen to be.

Our goal is to offer a friendly greeting, and provide professional results with the peace of mind that a family-owned local business can offer. We offer service and repairs on almost all standard makes and models of cars, trucks, vans, and more.

“I’ve taken vehicles here several times and always had a great experience and the prices are reasonable. Today I took my van in with a small problem and the manager just grabbed some tools and fixed it in about 10 minutes at no charge. Wow.”

Ron Yauk

I have been bringing all my family’s vehicles to DeMers for over 12 years. DeMers is the only shop I trust. They don’t try to sell me what I don’t need. The work is always done right. The work is done quickly. DeMers provides my family with top-quality maintenance and repairs, and they are honest and trustworthy.
