John Sullivan is a Los Angeles 🏷️#motorcycle-dealer and the co-owner of 📝Beverly Hills Ducati, the authorized 📝Ducati dealership at 428 N La Cienega Blvd that he and his wife, 📝Christine Sullivan, have owned and operated since 2002. The two took over a failing, run-down shop from its previous owner and rebuilt it into one of the country's award-winning Ducati dealerships — a turnaround the business attributes to a 📝motorcycle heritage running back generations. He is the dealership's named principal contact, and the business does trade as Beverly Hills Motorcycles.

Away from the showroom, Sullivan serves as tuner and mechanic for his son Errol Sullivan, a MotoAmerica Junior Cup racer who first rode at age three and has campaigned a Kawasaki Ninja 400 in the series with Beverly Hills Ducati among his primary sponsors. That racing calendar had him at Road America on May 30, 2020, when protests swept Los Angeles and looters worked La Cienega Boulevard; Christine Sullivan stood watch outside the storefront, unarmed, for roughly two nights until he returned to relieve her. The dealership came through unlooted.
