CarTreatments.com began as a hobby site but has expanded to so much more. Be sure to check out some of our articles on troubleshooting, car maintenance, and diagnostic trouble codes as well as our “Ask a Mechanic” page to get live help from a professional mechanic. 

While we encourage all our readers to leave comments and questions on any article with the goal of helping solve their issue, we unfortunately can’t answer every question simply due to time constraints. Fortunately, many readers have a good amount of car knowledge themselves and on many occasions have replied to the original commenter.

Meet Our Team

Mark Stevens – Owner

Mark is a veteran auto technician who has honed his skills with over 19 years of service working at various independent shops. While Fords and Mazdas are his specialty, he enjoys working on practically any vehicle (except a Nissan 300ZX).

He’s known for his attention to detail and problem-solving skills and enjoys coming up with out-of-the box solutions when the situation requires it.

Becoming an automobile technician just made sense after spending his childhood taking apart lawn mowers and other small engines just to see how they worked. Initially drawn to the repair aspect of the job, Mark has grown to embrace the challenge of diagnostic work.

When he’s not troubleshooting customers’ cars, you’ll most likely find him working on his current project (’96 Bronco) or cooking Italian food for his family.
