Kyle Mutz


My name is Kyle Mutz and I am the Director of the Justin Dart Jr. Student Accessibility Center. It is an honor to be here at the University of Houston helping to support the disability community with the privilege working at the center which recognizes the amazing work Justin Dart Jr. did for people with disabilities. As a person who grew up with a disability, I understand the challenges and obstacles that people face day to day. I have spent my entire career working to serve others and help empower them with education and awareness. As a former wheelchair racer athlete representing the United States, I have been fortunate to travel the world and experience different cultures and educate myself universally how disability impacts people. In my free time I enjoy spending time with my wife, dog Bella, friends, and family. I am also an avid gamer and adventure in trying new foods. I am dedicated to making the Justin Dart Jr. Student Accessibility Center the very best it can be for all students with disabilities and the University of Houston.
