GMS Elevator Services is a mid-sized facilities services firm based in San Dimas, California, operating in the elevator sector. Founded in 1987 by G. Mathew Simpkins, Pamela Simpkins, and Gordon Simpkins and incorporated in 1992, the company expanded from a family business into a broader elevator services provider. Its work spans installation, maintenance, repair, and modernization of elevators, and it has also manufactured custom elevator equipment and hydraulics. In 2014, GMS began refurbishing cab interiors, entrances, ceilings, and flooring as part of its modernization capabilities, and it established a structured safety program in 2003 aligned with state and federal standards for elevator mechanics and apprentices. The company serves both private clients and public-sector entities, including holding a Los Angeles Unified School District Small Business Enterprise certificate, and focuses on service, modernization, and new construction while managing projects from conception to completion.
