Customer-driven Mechanical, Electrical, and Plumbing engineering services.

The Mosher Group, colloquially known as TMG Engineering, is a Consulting Mechanical and Electrical engineering firm, headquartered in Edison New Jersey. The firm provides a broad range of engineering services for Architects, Owners, Civil Engineers, Manufacturing, Industry, along with many Local, State, and Federal Government agencies.

Frederick K. Mosher and the staff at The Mosher Group have long recognized the strategic and tactical advantages of a holistic, complete team approach to project management. It assures a higher level of quality, consistency, and ultimately client satisfaction and they have made this a cornerstone of the firm’s culture. This approach can be seen in the clients who have relied on The Mosher Group, some for over thirty years, along with many of the employees who have been there just as long.

Adherence to this unique approach to teamwork enables the professional engineers, designers, and draftspersons to efficiently and effectively complete any project. From the intricate electrical circuitry design in a half-million square foot network computer facility to the “intelligent” HVAC system in numerous high-tech laboratory projects, the team at TMG Engineering ensures engineering excellence.
