Gregory System International

Gregory System International was a chain of electrology practitioners. It was named after Dorothy Gregory, the electrologist who served as its director. They were involved in patents for laser hair removal, and they eventually added laser options in some locations.

The chain was founded in 1954 by Norbert Thomas, who built it to 12 clinics. His wife Marion S. Thomas took over the practice after he died in 1967. She built it to 20 clinics. Following her death in 1997, the chain appears to have disbanded, and the franchisees began practices under their own business names.
