Mark is highly involved in his community. As a longtime leader of volunteers with the San Antonio Rodeo, Mark lends his experience, strength and knowledge to the organization that helps so many youth in the community. He started at the age of thirteen volunteering for various organizations. and since then his vision recently brought a team of automotive industry together to create a community event called Carfest. As recently as 2016, Carfest donated more than $80,000 to local trade schools to assist youth pursuing a career in the automotive world. Mark also serves as a board member at Hidden Springs Youth Ranch, where he also donates the land that the youth ranches uses and  resources to maintain the facilities.
