His favorite part about his position is that no two projects are ever alike, as he is a person who enjoys overcoming the hurdles of a project from start to finish. Quite fitting to his problem–solving nature, he enjoys classic games that require lots of thought and strategy, from chess to backgammon to cribbage. Outside of work he also stays busy coaching youth baseball, softball, basketball, and his son’s Little League All-Star Team, who made it to the State Championship in 2024!

Outside of work, he stays active snowboarding, surfing, and playing soccer–and has even gone shark diving and can juggle.
