In Memory of our Founder, W. Thomas Musser

W. Thomas Musser
November 6, 1934 - July 9, 2016
Kennett Square, PA | Age 81

On Saturday, July 9 our beloved founder W. Thomas Musser passed away. Tom will be deeply missed by his family, friends, coworkers and community. He will be remembered as a true visionary, entrepreneur, and amazing human being.

Over 50 years ago, Tom, and his brother Dick, founded Tri-M in a tiny office space over a garage in Kennett Square, PA. What began as a two-person electrical construction company has grown into a premiere electrical solutions company with over 400 employees, 5 office locations and hundreds of long-term customer relationships. There is no doubt that Tom’s visionary instinct, attitude, professionalism and innovative ideas led Tri-M to where it is today.

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.

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.

In April of 2016, Tom was inducted into the Chester County Economic Development Council’s Hall of Fame. Below is the link to a tribute video; we encourage everyone to watch this to get a glimpse of Tom’s character and ideals.
