William (Bill) Frigon

William (Bill) Frigon grew up in Attleboro and was a long time resident of North Attleboro. After graduating from Attleboro High School in 1961, his thirst for knowledge led him to Northeastern University, Brown University, and Wentworth Institute of Technology, where he earned various degrees and certificates. As Director of Safety and Security for Thomas & Betts in Memphis, TN, Bill had the unique opportunity to travel the world. During his 42 years at the company, he had established friendships on six continents. His travels, however, did not deter Bill from raising a family with his loving wife Gail. Together they raised three sons. After Bill retired, his son, Wallace L. Frigon, Sr. (CEO and Founder of CSI), called upon Bill to serve as Safety Consultant for CSI. Our commitment to jobsite safety, paired with Bill’s immeasurable expertise, contributed greatly to the success of the company.

Bill was passionate about his community and the wellbeing of others. In addition to many years on the Executive Board of a local Boy Scouts Council, Bill served as trustee for a local charitable foundation dedicated to supporting area schools, hospitals, churches and businesses in the community.


Thomas C. Seibold Sr.

Thomas C. Seibold Sr. was a dedicated father to his two children, Kelly and Tom Jr., and a career Union Cement Finisher. He was equally committed to both his children and his trade. Tom grew up in Stoneham, MA and earned respect as one of the best Site Superintendents in the business. Being a true craftsman, Tom was an integral part of CSI’s development in its early stages. He was admired for his devotion to his children, and valued immensely as a colleague and friend at CSI.



Mark Vandette

Mark Vandette was the father of two young children, a devoted husband, and valued colleague and friend at CSI. He was a graduate of North Attleboro High School, where he excelled on the football field, and went out of his way to support his teammates. He went on to earn his Bachelor’s degree from Worcester Polytechnic Institute.

Mark’s strong faith compelled him to help those in need. In addition to raising money for various charities, he devoted his own time and money to the American Cancer Society. He was always prepared to lend a hand whenever his friends, family, church and community needed him.

At the young age of 27, Mark was diagnosed with Stage 3 cancer. After successful treatment, and a two year remission, sadly the cancer had returned. Never wavering in his faith, Mark lived each day with integrity and veracity in the face of such obstacles.
