How we got started at Mastin / Co-Man

Randy’s parents, Burton and Norma Mastin, started pumping septic tanks in the mid-1960s with their company, Bert’s Septic Tanks Service. Throughout the 1970’s, Randy helped his father with the family business while also racing motorcycles professionally at the national and international level. In 1977, Bert passed away due to complications from a work-related injury sustained while at Libbey-Owens-Ford Co., his second job. Norma, Randy’s mother kept the business for a couple of years before selling it to Randy and his wife Shirley.

In 1978, Randy Mastin Septic Tank was incorporated and has since grown and transitioned through the years from merely pumping septic tanks to completing installations and making septic tanks. Randy also started a garbage removal business in the late 1990s, but eventually sold it to a larger national company. In the early 2000s, he added another division to the company, Co-Man Portable Toilets, dedicated to renting restrooms.
