Meet The Team

David Samaha

CEO

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.

Mallory Bernard

An Auburn, AL native, Mallory spent many years in the construction industry as a project manager.  She met David when she decided to venture into the world of diesel ownership and needed a mechanic to work on her truck that was honest and could fit repairs into her hectic schedule.  From their friendship, she took an interest in his business and started working for the company full time in April 2018.  She likes to spend her free time riding, training and showing horses.

    This is my very first Google review. I normally do not have time to write something for others to read. I own a small business. Like all small business owners, I work very hard, and a lot of hours. I need my diesel truck every day, If I don’t have it, I don’t get paid. It is extremely difficult to take time to keep it maintained. I have used Diesel David three times from fixing a problem to regular maintenance. They come to your location, so you don’t miss time on the job site or your place of business. David, Seth and Mallory are all great. They do awesome work at a fair price. anytime I have an issue or simple maintenance, I will call Diesel David to do the work.

    A higher quality experience than any auto shop. David was great to go through every detail of the work and make sure I knew exactly what was going on with my car. They did a detailed job for me today that ended up going way past the estimated time. I was worried they would present me with a huge bill, but instead they stood by their estimate and kept their prices low.

    I was really happy with their prompt service they showed up when they said they would they did the work they said they would do. And they were fast and efficient on the job. They showed me what was wrong so I knew what they were going to do to my truck. I would recommend them they are honest and there prices seem fair. Thank you for your help to get me back on the road so I can make money again.

    We've known David for many years and have always thought very highly of him. One recent repair required a great deal of research but once David fixed it our car stops better than it did when new!. We are very pleased with David's professionalism as well as the results!

    So I'll paint the picture for you guys: it's Saturday evening, and I'm traveling though Georgia after a conference when my truck breaks down on the side of the road. I look up dealers and mechanics near me but they're all closed until Monday so I search for a traveling mechanic and find Diesel David's. I call and even though I didn't connect the first time, David sends a text like I'm his old friend saying "This is Diesel David, is everything ok?" After speaking with him I find out that I'm a long way out of his service area. Nevertheless, David takes time out of his day to listen to my issues and come up with a plan to get me back on the road. 20 minutes later I've got some insight into my truck's problem and within an hour I'm on the road. David also checked in on me hours later to make sure my truck making it. Even though David didn't turn any wrenches for me I can tell he's a stand up guy with bonafide integrity. If I'm ever having trouble and I happen to be in his service area I would definitely give him a call.

    David has worked on our old 98 dodge diesel a few times now and always professional, delivering top notch service and repairs. Both onsite repairs and at his shop. Does what he says ahead of schedule, at a fair price. Highly recommend. Guarantees his repair work, which is great as a consumer looking for good value. i was particularly impressed in the onsite repair he did for us as we were located almost 70 miles from him. Amazing value for the work given he had to drive so far across town.

    Friendly, honest people that did a lengthy test drive with my mothers truck and actually showed us what he had found. Being a mechanic without a shop it was nice to have someone that didn't beat around the bush. And cost wasn't unreasonable.

    Diesel David is my hero! Ford misdiagnosed my engine code and wanted me to get work done David already did and under warranty (which we found out didn't need it!!) - mind you my car was with Ford for 10 days with no answer. I called David - he new exactly what it needed. He knew I was really anxious and always answered my calls and questions (that means a lot to me). This is the 3rd time using him. I TRUST him.

    My car has been making this God awful squealing when driving down the road, a cringe worthy squeal that has all the other drivers on the road glaring at you (imagine nails on chalk board x100). So yesterday I stopped at a well know shop on my way home and they pulled my car in and within 5 minutes the mechanic told me I needed new rotors and brake pads (even though my pads were changed about 6 months ago). The mechanic told me my pads were metal on metal and my rotors were warped and could not be turned or refinished. I left completely frazzled and stressed out with dollar signs swirling around my head after the quote given to me.

    A friend of mine recommended Diesel David Inc to do the work and he provided a quote much lower than the above shop and he could do it after work tonight (not having to miss work for car repairs is always a plus). So I get to David’s shop and he gets my car on the lift and pulls the tires off to find that my rotors are fine and my brake pads are not nearly as bad as the previous mechanic described. Instead, he found the brake wear indicator had broken off and was grinding against the pad and rotor (or something to that nature anyways). He literally broke the little metal tab off and said alright, you are fixed and good to go. I just stood there with my jaw dropped. Had I just gone back to the other shop they would have robbed me blind. David literally saved me hundreds of dollars that I didn’t even haven’t begin with. So with all that said, if are looking for a ceriftifed, reputable, honest, and affordable mechanic, David is your guy! He isn’t just after they money like so many others. He has made a customer out of me!
