Our Founder

W. Thomas Musser W. Thomas Musser, Founder (11/06/1934 - 07/09/2016)
Tom believed that business has the responsibility to give back to the community where we live and work, and he embodied that belief. He has helped improve the lives of many Chester County families by supporting many charitable organizations, leading capital campaigns and serving on the board of many service and civic organizations. He has contributed to political organizations and grass roots campaigns and was an advocate for small business and free enterprise.

After majoring in electrical engineering at the University of Florida and serving his country in the United States Navy, Tom returned to Pennsylvania and along with his brother, Dick, founded Tri-M Electrical Contractors.

Early on, Tom bought out his brother and set out to grow his business into one of the leading electrical and building automation contractors in the eastern U.S. After 34 years of expanding his company and achieving his goals, Tom sold Tri M to Encompass Services, Inc. Within a few years, he took the lead in buying his creation back, and served as its Chairman.

Tom lived by “always be thankful, but never be satisfied.” He was thankful for his family, his country, his freedoms, his employees and customers. Tom’s vision, passion and entrepreneurial spirit motivated others to be their best and not be complacent, and forged the growth of Tri-M.

Tom was a true leader, and he led by example. He was a man of integrity, honesty and believed in the value of hard work. He made it a point to learn an employee’s name and family. He welcomed anyone into his office if they had a question or concern. He would work alongside of you, and there was not one job that he considered beneath him.

Tom has held a number of executive positions with the Associated Builders and Contractors, including National Chairman. He was Chairman of the National Federation of Independent Businesses, Vice Chair of the U.S. Naval Institute and on the Department of Defense's Advisory Board for Employer Support of the National Guard and Reserve. Tom has also served on the Chamber of Commerce and many other business and service organizations.
