An avid sports fan, he was passionate about Philadelphia sports and loved to attend games, especially the Eagles and 76ers. He played basketball within the HHoops league and baseball for the Horsham Little League. He was ambitious outside of school, starting his first job at age 14 at Tonelli’s Pizza in Horsham. Most recently, he worked at Ann’s Choice Senior Living Community in Warminster.
