When he is not working, Matthew spends time with his wife and three boys. He loves to keep up with the latest in sports, especially the Spurs, and Los Angeles Chargers and Texas A&M Aggies, as well as the Cowboys, Texans, and Astros. Matthew loves exploring new restaurants, parks, and museums, and enjoying all the family fun San Antonio has to offer.
