Our History

D&G Machine Products, Inc. is a privately held company.
Ron Denyer & David Gushee founded D&G in 1967 in a one-car garage behind Dave's house. They specialized in producing custom tooling for Power Generation equipment manufacturers located in and around Portland, Maine. As the small 2 man operation started to grow, the first actual shop was opened in a small shack, on the docks of the South Portland side of Portland Harbor. The startup cost of starting a new machining business forced Ron into turning over his ownership to focus more on his family, although he stayed on and led the company's engineering department as Chief for 20 years. Dave soon hooked Fred Loring into taking a small risk in assuming Ron's ownership. Dave and Fred became partners for 20 yrs, they combined fabrication and machining services which defined the foundation of which D&G was built upon over the next 20 years

By 1972 D&G had outgrown their original home on the docks of Portland Harbor, so a move of operations, to a site around the corner on the South Portland waterfront facing Casco Bay, made a perfect fit as it was also closer to the GE Plant, D&G's number one customer at the time. This move inked D&G's trademark as truly a Maine manufacturing based company known to many as— "D&G by the Sea". In 1987 Fred Loring left the company applying his talents in the local food supply markets. Dave Gushee then joined a new partnership with four key company individuals, Chuck Tarling, Ken Pritchard, Steve Sullivan and Duane Gushee. The four would go on to build D&G Machine products into a National Manufacturing Power servicing all the major industries in America.. By 1993 they had outgrown the South Portland facility and then moved the company to its present facility in Westbrook, Maine. In 1996 Dave Gushee retired leaving full ownership of D&G to the four partners. By 1997, D&G had outgrown the 65,000 sq-ft Westbrook facility, and added 35,000 additional square feet. And then again, in 2005 D&G added an additional 55,000 sq-ft facility at 20 Hutchinson Drive Gorham, Maine — the new home of D&G Fabrication and Sheet Metal Manufacturing Facility.

By 2012, after contributing many successful years to D&G, Duane Gushee and Ken Pritchard retired from the company. With Chuck Tarling and Steve Sullivan spending much of their time out on the road focused on business development, Charlie Tarling was promoted to Partner to manage business operations. Charlie became the third President of D&G Machine Products behind Dave Gushee of 29 years, followed by Duane Gushee of 16 years. In 2017, D&G Machine Products, Inc. proudly achieved 50 years in business, well-established as a State of Maine Manufacturing Company. Over the 50 years, D&G has expanded to producing precision products and assemblies for all major industries in our nation with a long list of signature customers. Chuck, Charlie, and Steve annually invest in many local manufacturing youth apprenticeship programs. As they all started in similar programs, they believe that partnering with local high schools and colleges to develop the talent required will advance our trades into the future. At D&G, our operation philosophy is that of continuous process and quality improvement. Employee participation, involvement and commitment to this philosophy is rewarded with excellence in customer satisfaction. D&G produces products that are in everyday technology including: Computer Chips, Paper Mills, Power Plants, Medical Equipment, and Military.
