Our Journey Began with...

A vision to create a one-stop shop for diesel services, and today, we proudly stand as a testament to that dream. Our team consists of eight highly skilled mechanics and three fully equipped service mobile trucks, ensuring prompt and efficient service.

At the heart of Hex 6 Diesel Services are our founders, Gary and Sarah.

Gary is a dedicated professional with a rich history in the diesel and automotive industries. His journey began in the military, where he honed his skills as a diesel mechanic. His passion for the field led him to pursue a degree in diesel and automotive technology.

He also holds a degree in business management to complement his more technical side. His leadership skills developed even further through his role as a general manager at two large dealerships. When Gary moved to Texas, this marked a significant turn in his career, where he managed equipment in the oil industry. This diverse background gave birth to Hex 6 Diesel Services, starting from a humble shop on our property. Now, our facility spans 19,000 square feet on a sprawling 26-acre plot of land.

Our other co-founder, Sarah, brings her own unique set of skills to the table. With her background in education and her degree in teaching, Sarah expertly handles all the marketing and parts management aspects of the business. Her keen eye for detail and organizational skills ensure that our operations run smoothly and efficiently.

Of course, we would be nothing without our team of eight highly skilled mechanics, parts, and service advisors. Each member comes from a different background, bringing their own individual set of skills to the shop floor. These include ASE master-certified mechanics, welders, and certified diesel technicians with dealership experience and extensive training in various applications.

We are also proudly veteran and family-owned, Hex 6 Diesel Services is also in the process of obtaining certification as a woman-owned business.

Our Customer Reviews

See what our recent customers are saying about our services.

Second repair to my 30HP Kubota at Hex6. Axle issue first and steering second. Timing was good to complete considering their shop load. Cost in line or better than other options. Good staff. Most pleased overall.

Duane Nash

Wow, what a great Company. Caleb was in constant contact and the bill came out much less than the estimate! The technician was on time, very knowledgeable and the job was done quickly. I will use them every time for my tractor work! Thanks Hex 6!

Sherry Young

Hex 6 did a great job on my work truck. They did a full in frame rebuild. The service was fast and my truck has never run better. I took it back for regular schedule PM and they had me in and out the next day. Will only use them moving forward!!
