Our Story & Our Commitment to Trusted, Reliable Service

About Gregory & Martin Inc. (GMI)

In 1992, Mike Martin, owner of Gregory and Martin Inc. (GMI), asked Barrie Gregory to join his team to add to his expertise in plumbing. That same year, Mike officially established Gregory and Martin Inc. Over time, he grew the company into one of the leading, go-to service providers in the area.

Building strong customer relationships has been the backbone of GMI’s success and continued growth. GMI provides service to both residential and commercial customers. With 10 full-time employees, GMI has the knowledge and know-how to service and repair nearly anything presented to the team.

GMI is always looking to grow and welcomes highly motivated individuals who are interested in building a long-term career with the company.
