Arnhold has supported EQUI-KIDS Therapeutic Riding Program, an organization that offers therapy to people with mental and physical disabilities, since 2002, when he and his partner donated 92 acres of land for its move and expansion. He supervised the facility’s construction, including an indoor horse-riding arena to allow therapy year-round. He has also headed the Capital Campaign and raised more than $3 million for the organization. Currently, 70 students a week work with the horses to improve self-confidence, fine motor skills, balance, concentration, and social skills.
