"Best auto repair/tow shop ever! The lengths they went to help me out was incredible. Hard to find people that are this great anymore. Lucas even gave me rides to and from my hotel due to my car being down. Do yourself a favor and call no other shop around!"

About J&R Service Center
Family-Owned Since 1996
At J&R Service Center, we’ve proudly provided quality repairs and honest service to Diamond, Gardner, and surrounding communities since 1996. Founded by Jeff Lee, a Master Technician by age 21, our shop quickly earned a reputation for getting the job done right the first time. Our family-owned roots and commitment to treating every customer like family remain the foundation of our business today.
Two Locations, One Commitment to Excellence
With two convenient locations—Diamond specializing in general auto repair and Gardner offering both complete auto repair and medium- to heavy-duty truck services—we’re equipped to handle everything from personal vehicles to commercial fleets. Whether you need routine car maintenance, diesel diagnostics, heavy-duty towing, or emergency roadside assistance, you’ll receive the same trusted service and expert care at both locations.
A Legacy Built on Quality and Trust
What started as a small two-bay shop in Gardner has grown into a trusted multi-location service center known for solving problems others can’t. Since 1996, J&R Service Center has built a reputation for honesty, friendly service, and quality repairs that stand the test of time. Many of our original customers still rely on us today, a reflection of the lasting relationships and trust we've earned over the years. We are proud to still offer the same personal service that helped build our foundation.
Committed to Our Community
Supporting our community has always been at the heart of what we do. We proudly sponsor local sports teams, participate in food drives, and donate to area fundraisers and charities. When you choose J&R Service Center, you're not just choosing expert auto repair—you’re supporting a local business that gives back to the community it calls home. We believe strong communities are built by businesses that care beyond the doors of their shop.
