Born in Buffalo, New York, Shaun moved to Texas with his family in 1992, and aside from brief stints living in Ohio and North Carolina for work and school, has made it his home ever since.  Shaun is an avid sports fan and outdoor enthusiast, and met his significant other, Chelsea Owen, playing ice hockey.  When he is not working, playing sports, or spending time with his dog Howdy, you will most likely find Shaun in the kitchen, by the grill, or carefully tending to his BBQ smoker.
