Who we are

We are a locally owned and operated business, serving the Tomball, Magnolia and surrounding areas for all their diesel auto repair needs with over 20 years of experience!


I was so lucky to have stumbled upon Tomball Diesel and Auto, as a female I have always been treated like I didnt know a thing about auto mechanics.  Sean and his crew listened to me and made me feel like a long time customer. Their work and prices are top notch.
