Mark S. Colaw


Seymour's Garage Staff - San Antonio, TX

A native of San Antonio, Mark has a passion for the automotive industry. He started working for the shop's namesakes, Hastings and Ida Seymour, as one of three people who knew how to run the new diagnostic machines. Mark eventually purchased Seymour's Garage in 1985, and opened the current location in 1988.


Mark is highly involved in his community; as a longtime leader of volunteers with the San Antonio Rodeo and recently was inducted into the S.A.L.E Hall of Fame. Mark lends his experience, strength, and knowledge to the organization that helps so many youths in the community. He started at the age of 13, volunteering for various organizations, and since then his vision recently brought a team of automotive industry professionals together to create a community event called CarFest. As recently as 2017, CarFest donated more than $100,000 to local trade schools to assist youth in pursuing a career in the automotive world. Mark also serves as a board member at Hidden Springs Youth Ranch, where he donates the land that the youth ranch uses and resources to maintain the facilities.


At Seymour's Garage, we are committed to providing quality service using high-tech diagnostic methods and doing the job right the first time. For nearly 50 years, Seymour's Garage has been an innovator and implemented many cutting edge procedures and processes to cut costs and keep your vehicle running great.

 When Joseph was still in high school, he brought his truck into Seymour’s Garage for repair. He had always worked on his own truck and really enjoyed it; he loved working with his hands and his head at the same time, and knew then that a desk job was not for him. A while later, he brought his truck into Seymour’s Garage again to have the rear end diagnosed. Mark, owner of Seymour’s, test drove Joseph’s truck that day. Joseph took this opportunity, and time with Mark, to ask some questions about entering the automotive world. Mark told him to “define your direction,” and “go to school, get some experience and come back to see me." Joseph left that day feeling determined. He finished high school, completed his college program, and went to work for a local shop. After getting married, buying a house, and a couple years of working at an automotive shop, he decided it was time to head back to Seymour’s Garage. With resume in hand and no appointment, Mark agreed to meet with the young man in the lobby. Joseph asked Mark if he remembered him and after recounting the story from a few years prior, Mark did! Mark was impressed with Joseph’s drive, determination and skill set and hired him to be part of the Seymour’s family where he has been since!
