Michael D’Angelo Sr., Chairman

Sitting at the head of the table at A & H Duffy is Mike D’ Angelo, Sr. who has been with the company since 1974. Mike took a hands-on interest in the company early on, and over time worked in virtually every position and on every line. When the opportunity came in 1995, Mike took a bold step and bought A & H Duffy. Just two years later he started MCM Technologies. After getting both companies well-situated Mike proceeded to take advantage of another opportunity and purchased Quality Spraying Technologies in 2004.

Mike, Sr. resides in East Greenwich, and when he does take time to enjoy himself away from business, you’ll find him traveling to regions far and wide.

Michael D’Angelo, Jr., President

Mike D’Angelo Jr. started with Duffy working summers during high school between 1994 and 1997. By that time he had become fully qualified to come on board as the manager of the Lincoln, RI location, and served in that capacity until he was promoted to Vice President in 2001. He took over the reigns as President of A & H Duffy in 2009. In addition, he holds the position of Vice President at Quality Spraying in Providence.

Born and raised in Lincoln, Rhode Island, Mike now resides in East Greenwich where he enjoys spending time with family and friends. Mike is an avid Pats, Celtics and Red Sox fan.
