Jay Moser took the reins at Duffy’s Auto Service in 2016, carrying on the shop’s tradition of exceptional automotive care. Jay’s passion for cars began at an early age, working alongside his father, a skilled mechanic, who taught him the fundamentals of auto repair. His experience grew while working for a parts supplier, where he collaborated with auto shops of all sizes, gaining invaluable industry insight and fostering his dream of owning his repair shop.

Outside the shop, Jay enjoys golfing, spending time with his dogs, and traveling. Under his leadership, Duffy’s Auto Service has expanded to offer a multitude of services. We serve as a true dealership alternative.
