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.
Mark Sirois – Production Manager
Mark Sirois got his start in manufacturing as a polisher for VH Blackinton in North Attleborough. There he learned the ropes and expanded his background and knowledge of production, expediting and quality control.

In 1996 Mark joined AH Duffy as Production Supervisor, and just a year later became Plant Manager at Duffy’s Syracuse, New York location.

In 2001 Mark stepped into the role of Production Supervisor at A&H Duffy’s flagship location in Cranston, RI, where he oversees and directs overall, day-to-day operations, dealing with scheduling, shipping, quality control, production and customer service.

Joe D'Angelo – Vice President
Joe D’ Angelo, Vice President of A&H Duffy came into the finishing industry as a polisher some 40 years ago, learning the business over time from the ground up.

Later, he stepped into the role of project manager for the team that put together the MCM Technology facility in Syracuse, New York. Joe also consulted for Alcoa during the set-up of that company’s Ohio Robotic polishing line for aluminum wheels.

Joe’s unique background has been instrumental in building Duffy’s design and production team where his product knowledge is supported by his studies in Industrial Engineering at URI.
