Joseph M. Cassin

Joseph M. Cassin, 82, of Rye, NY, died peacefully at home with his wife of 58 years by his side, Joyce S. Cassin, after a heroic battle with cancer on Wednesday, January 22nd 2025.
Joe was born in New York City on June 23rd 1942, to William F. Cassin and Anne M. Cassin, and was raised in Larchmont, NY as the middle of five boys, William, John, Michael and Richard. Joe was educated at St. Augustine School before matriculating to Iona Preparatory School and Mamaroneck High School, from which he graduated in 1960. He then attended Georgetown University (class of 1964), followed by Fordham University Law School (class of 1967). Both schools held a special place in his heart, and he remained devoted to both universities for his entire life. After passing the bar exam, Joe worked as an attorney in New York City before founding his own law firm, Cassin LLP, in 1986 from which he retired at the end of 2022.
Joe was a devoted and loving father to his daughter Keelin Cassin Pye and his son J. Matthew Cassin Jr. who dearly miss him and the life lessons he imparted to them. Among them was to always know "that God helps those who help themselves." Joe took tremendous pride in the fact that both his children followed in his footsteps and are also proud and active alumni of Georgetown University.
Joe was the ultimate people person, with a spirit of generosity that was second to none. One of his greatest gifts was the numerous young people he embraced and guided throughout their careers. Being a father and a grandfather was Joe's true passion and calling and spending time with his kids and five grandchildren were his happiest and proudest moments.
Joe was preceded in death by his parents William F. Cassin and Anne M. Cassin, as well as his brothers William and Michael Cassin, and is survived by his wife, Joyce, brothers John and Richard Cassin, children Keelin Cassin Pye and J. Matthew Cassin Jr, daughter in law Holly Shaw Cassin, son in law Christopher Pye, and grandchildren Ryan, Rory and J. Matthew Cassin and Christopher and Campbell Pye, as well as many loving nieces and nephews.
A catholic mass celebrating Joe's life will be held at the Church of the Resurrection in Rye, NY at 11:00 am on Thursday, January 30th. In lieu of flowers, donations in his name may be made to the Church of the Resurrection, Rye, NY.
