He served as a 2015 White House Intern for former President Obama and after began managing the ground efforts for ballot initiatives and State and Federal races in Texas, Nevada, Ohio, Pennsylvania, Georgia, and Virginia. His compassion and drive to help positively impact his community also saw him assist in managing disaster relief efforts for FEMA in the wake of Hurricane Harvey and Hurricane Maria.
