He was born in New York and grew up in Oakland, California. During his youth, he owned and trained dogs and horses, played youth football with the Oakland Dynamites, and participated in equestrian sports, including jumping, dressage, vaulting, and trail riding. At Oakland High School, he played football and was an Oakland Athletic League wrestling champion for four years.
