About Us
At Colorado Engine & Complete Auto Repair in Arvada, CO (5870 W 56th Ave), our story is built on family, experience, and a commitment to doing right by our customers. For over 40 years, we’ve proudly served Arvada, Wheat Ridge, Westminster, Lakeside, and nearby North Denver communities.
A Family Legacy Built on Engines
Our journey began when George Anderson founded the business as an engine wholesale distributor. Over time, that foundation naturally evolved into a specialized engine installation shop.
Auto repair has always been part of our family’s DNA. Today, that legacy continues under the leadership of Kara and Rory Hamersky, who purchased the shop from her father and have been helping guide its next chapter. With a deep respect for the business her dad built, they have brought fresh energy and vision, expanding services while staying true to the values that made the shop successful in the first place.
Growing Into a Full-Service Auto Repair Shop in Arvada, CO
While we’ve long been known for engine replacements and major repairs, Colorado Engine & Complete Auto Repair has grown into much more than that. We’re now a true full-service auto repair facility serving Arvada and Denver, CO, handling everything from oil changes and maintenance to diesel engine replacements and diagnostics for personal vehicles and fleet vehicles.
One of our goals is to make sure customers know they don’t have to go anywhere else. We’re also proud to be a trusted second-opinion shop. Many customers come to us after being told they need costly replacements, only to discover that a proper diagnosis and the right service can solve the problem without paying extra. That honesty is something we take seriously.
