Our Story

Welcome to Mastertech Auto Repair, where we pride ourselves on providing top-tier automotive service with a personal touch. Founded in 2003 by Kevin and Heather, our family-owned and operated business has built a stellar reputation in Green Bay, WI, and the surrounding areas, including Howard, Bellevue, Suamico, De Pere, Appleton, and Kaukauna. With 23 years of dedication to excellence, we treat every customer like family, ensuring that each visit is met with care and professionalism.

Kevin’s journey began humbly, working out of his garage with a passion for cars and a commitment to quality service. As demand for his expertise grew, he transitioned to a small two-lift building, where he continued to expand his skills and offerings. Over the years, Mastertech Auto Repair evolved from that modest start into two fully equipped locations, each designed to meet the diverse needs of our valued customers. This growth reflects our commitment to providing exceptional service and our ability to adapt to the ever-changing automotive landscape.

At Mastertech Auto Repair, we specialize in both import and domestic vehicle repairs. Our expertise spans a wide range of makes and models, including luxury brands such as Audi, Porsche, Jaguar, BMW, and Mercedes. Whether you need routine maintenance, complex diagnostics, or extensive repairs, our certified technicians are equipped with the knowledge and tools necessary to get the job done right.

Our comprehensive service offerings include engine replacements, transmission repairs, tire services, suspension work, wheel alignments, brake repairs, and much more. We understand that your vehicle is not just a mode of transportation; it’s an essential part of your daily life. That’s why we go above and beyond to ensure your car operates smoothly and efficiently, providing you with peace of mind on the road.

Customer satisfaction is at the heart of everything we do. From the moment you walk through our doors, you’ll be greeted with warmth and professionalism. Kevin and Heather are actively involved in day-to-day operations, ensuring that every customer receives personalized attention. We take the time to listen to your concerns and provide clear explanations about the services needed, helping you make informed decisions about your vehicle.

At Mastertech Auto Repair, we also believe in transparency. We provide detailed estimates before any work begins, so you know exactly what to expect.

Testimonials

On 2/26/2026 La had this to say:
Got 3 diagnostics from other places and they all guessed on why i had a misfire. One phone call with Mastertech and they knew what the issue was without even looking at my car yet. Fixed it in a two days after 3 years of the constant misfire. Significantly cheaper than any other place as well. Very very knowledgeable and they explain things in a way i could understand. Highly recommend! Testimonial written by La on this site.

On 7/20/2025 Angela Knight had this to say:
Posting for my neighbor: Patriot Express Tire & Oil just completed a major repair to my 14 year old Avalon. Having been a customer for years with other repairs, I was confident in the quality of the their repair work and professional advice. They even documented the needed repairs with pictures of the damage parts. I am grateful for their kindness in updating me on the progress and appreciate their efforts. Landon and Aaron went over and above my expectations to complete the work. Thank you again Sherill Lazar

On 8/18/2024 David g. had this to say:
This is the type of shop that everyone hopes to find. Have been in a few times for oil changes and suspension work. Last visit they cleaned up a sensor that I thought needed replacement. Many shops would have just installed new and I would have been none the wiser. Saved me 400$. Highly recommend.
