Who is Diesel David?

Your Local Mobile Mechanic

My name is David and I am an ASE Certified Technician. In 2014, I started a truly awesome service that eliminates the frustrations of working with a repair shop. My services are 100% mobile, yup, you read that right. My customers love me, because I save the time, money, and heartache. No more waiting rooms, no more sheisty mechanics, and the best part is you get to drive your car or truck with confidence!


Imagine yourself feeling good about calling your mechanic, and never having to stress about your vehicle working properly again.

Meet The Team

David Samaha


David discovered his love for all things mechanical when he was 6 years old.  He rebuilt a go cart with the help of his father who provided transportation to pick up parts and special tools.  This carried on through high school where he completed the automotive dual enrollment program his junior year.  He graduated early and proceeded to start the AAAS(Automotive Associate Applied Science) program at CTC.  Book an appointment and talk to David further about his adventure into the world of diesels and his love of all things mechanical.

Seth Buckner

Lead Technician

Seth has been working on diesels from a young age.  He started with his family’s trucking company, performing tasks from preventative maintenance all the way to full engine swaps.  His accreditations include numerous ASEs and several diplomas in DOT inspections and maintenance, diesel electrical systems troubleshooting/repair and diesel engine rebuilds.  He loves his country and prides himself in working for a small company pursuing the American dream.

    David and his staff were very professional and knowledgeable. We brought our F250 to him for brakes and cruise control issue. His prices are very reasonable and he stands behind his work.
    I would definitely refer to my friends and family.

    Excellent service, quick and professional! David is responsive and very conscious of your time and schedule. He comes and works on my car while I am at the office and I never have to drive to the shop. As convenient as it gets!

    David and Mallory and crew took excellent care of me and my truck. Having damages from severe fuel contamination, they worked with my insurance company under comprehensive coverage and kept me well informed throughout the entire process. Repairs were completed quickly and efficiently and my truck once again drives great. Excellent shop that does excellent work and run by great people!

    Recently purchased a diesel with some issues and David diagnosed the problem in our driveway. We left the car with him while on vacation and it now runs like a dream. It’s so nice to have an honest, knowledgeable company near us and we will only call David for any future needs for both our diesels.

    Diesel David has been great for my partner and I’s Tree Service. We bought a bucket truck sight unseen. After our truck spent over a month in another diesel shop, we needed another repair and called Diesel David. Not only did they send me a estimate before hand but once we decided to go ahead with the repairs they got right on it! Quick response, great service, very knowledgeable and fair pricing! We will continue to use Diesel David for all our medium duty needs!
