He attended Northwest Vista College and the University of Texas at Austin.
Based on his own life experiences, Dennis wrote the screenplay for Strings while working at TSTV, the student television station at the University of Texas where he created and acted as show runner for the award-winning sketch comedy program, That"s Awesome! starring Zach Anner. Following the release of Strings in May 2012, Dennis embarked on a 282-day cross-continental motorcycle trip on his KLR650 dual-sport motorcycle. He rode from his family"s home in Boerne, Texas through all of Mexico and Central America before sailing around the Darien Gap and concluding his journey through Colombia, Ecuador, and Peru.
Dennis"s trip nearly ended in tragedy when he was hit by a drunk driver in the Andes mountains outside of Potosi, Bolivia and left for dead until he was rescued by a local family.
He finished the last 56 miles of Bolivia with a broken wrist and sold his motorcycle on the Bolivia/Argentina border, before hitchhiking to Ushuaia, the southernmost city in the world, then catching a boat to Antarctica. Dennis wrote a screenplay based partly on his experiences entitled ENDURO, currently in pre production.
