Daniel J. Mastellon

October 11, 1952 ~ April 11, 2022 (age 69)


Daniel Mastellon is survived by his wife, Margaret Mastellon, his two daughters, Kelli Vasquez and Theresa Mastellon, and his two living step-sons Vincent and Michael Costanzo. He leaves behind 5 grandchildren - Vanessa and Peter Costanzo, Kathleen Costanzo and Mia and Emmie Vasquez. Though he lost both his parents and his step-father, he also leaves behind his loving brother Kevin Mastellon, Kevin's wife, Kathleen Mastellon and their daughter, his beloved niece, Ticia.
Dan lived his professional life as a Sale Executive but focused his personal life on his love of music (as a former drummer, the Allman Brothers was his favorite band), his love of golf (Kelli and Theresa's Saturday morning memories always include endless rounds of golf on TV), his never-ending commitment to and love for the New York Mets (from season tickets during his professional career to annual Mets/Yankees games with his daughters) and his love of his wife, children, grandchildren and extended family.
He grew up in Cambria Heights, NY and married Barbara Kelly, fathering his two daughters, Kelli and Theresa. Following their divorce, he re-married to Margaret Costanzo and remained with her for the rest of his life. They just celebrated their 26th wedding anniversary. While Dan and Margaret did not have any children of their own, Dan loved his step-sons Vincent and Michael and his late step-son Peter, like his own.
Dan, while a natural-born extrovert, was also a very reserved man who spoke in meaning, observed from the side and spent alot of time behind the camera, capturing memories with his family. He shared his love of photography and baseball with his daughters, who carry on those traditions with their families. 
He was also quite the handyman and not only built and refinished much of his own property, but also worked side-by-side with Michael and Vincent refurbishing old pieces for clients. His craftmanship was superb and Theresa and Kelli recall many memories of weekends spent wandering the aisles of Home Depot, the smell of sawdust being a key memory of their father. 
Friends recall a light-hearted man whose friend list was endless and extended family referred to him as their brother. He will be sorely missed by all who love him and his memory will live on in their hearts forever.
