Bill's Appliance Repair In 1987, on Catalina Island, while owning a coin operated laundromat, we started servicing appliances. Shortly thereafter, we moved to the Eastern Sierra in 1995 and started Marvin & Sons Appliance and soon incorporated Bill's Mammoth Appliance and Bill's Appliance and Video into our company. We service the complete Eastern Sierra, which includes all of Inyo and Mono counties, Bishop, Mammoth Lakes, and the Tonopah and Round Mountain area of Nevada.
