HISTORY

​The Tri-M Group, LLC was founded in 1964 by two brothers, Tom & Dick Musser, it has grown from a very small local, industrial and commercial electrical contractor to one of the region’s largest merit shop contractors.  Through the decades, Tri-M recognized the growing and changing services needed by our customers; therefore, Tri-M has a very diversified service offering.

In 2002, Tom Musser, Chairman and Jim Horn, CEO/President became joint owners in the Tri-M Group. Tri-M celebrated its 50th anniversary in 2014 – a true milestone in the construction industry. From its inception, Tri-M has been dedicated to excellence in every aspect of our business, starting with the treatment of our employees and carried on through to our customers, vendors, and in the communities in which we work and live. To ensure Tri-M’s future, the ownership was expanded in 2016 by adding Executive Vice Presidents, Ron Bauguess and Chris Peirson as partners. While expanding our services; Tri-M has never lost sight of our founders’ drive to provide opportunities for employees and build long term relationships with our customers.
