Duane took the greatest pride in being a father. A devoted New England sports fan, he enthusiastically supported all four Boston teams, with a special love for the Bruins and the Red Sox. He passed his passion for hockey on to his son, Sean.

In addition to following sports, Duane enjoyed camping, taking cruises, attending Red Sox spring training, and making trips to Las Vegas. He proudly served his country in the Air Force for 28 years and later worked for Quincy Elder Services, where he continued his commitment to helping others.

Duane was predeceased by his late loving wife Maryellen Slattery. He was the beloved son of the late Paul Slattery and the late Mary (Hudson) Slattery. He is survived by his son, Sean, as well as a sister-in-law and many brothers-in-law, cousins, nieces, and nephews who will cherish his memory.

He will be remembered for his dedication to family, his service to his country, and the joy he found in sharing his interests and adventures with those he loved.
