Dennis James Sullivan born March 2nd, 1954 in Malden, MA to the late John Sullivan and Olga Panasuk entered eternal rest on May 8th 2021. Dennis was a long term Malden resident, until the latter years of his life, where he resided in Nashua, New Hampshire. As a proud member of his community, he was passionate about advocating to maintain the historical essence of the city. In his ninth grade yearbook, he noted that he wished to be a sportscaster. This passion for sports held true throughout his life, as he was a dedicated fan of all New England sports teams and would regularly call his sons to give play by plays of each event. He was a graduate of Malden High School's class of 1972 where he was a devoted hockey player for the Tornadoes. He worked for Porter Radio Shop throughout his teenage years for John and Margaret "Peg" Porter and remained a devoted family friend of theirs until their passing. He was a dedicated police officer and Union President for the Malden Police Department for many years. He was appointed as a dog officer for the MPD in March of 1975, went on to become a Reserve Officer in March of 1980, and became a police officer in April of 1984. Dennis went on to retire from the MPD in November of 2000. He was known to fellow officers as the self proclaimed "Ninja Cop". He was a man who lived life to the fullest, and had a special and unforgettable presence. He enjoyed gardening and fishing with his family and friends. He was always the life of the party. His stories, jokes and contagious laughter could light up any room. He was a genuine man who would willingly give you the shirt off his back. His children, family, and grandchildren were the light of his life.

He is survived by his five loving children and their spouses, Christopher and Nicole Rabideau of Medford, MA, Joseph and Tina Sullivan of Derry, NH, Kelly and Joseph Mazzone of Nashua, NH, Kara Kathleen Sullivan of Naples, FL, and Michael Patrick Sullivan of Salem, MA. He is also survived by his five grandsons, Jackson, Joseph, Benjamin, Joseph and Maxx, as well as his former wife who he remained very close to until his passing, Maria Caruso. He is survived by his three siblings and their spouses, Michael and Judy Sullivan of Malden, MA, James and Dana Doyle of Wilmington, MA, and Carollee and Harry Ayan of Windham, NH., as well as his nieces and nephews who were held close to his heart, Tony, Taryn, Erin, Adam, and Darlene. His aunt Carol, close cousins Carol Ann and Martin Gately, and Chuck and Muriel Brandano, as well as lifelong friend Billy Griffin meant the world to him. Dennis also had many loving aunts, uncles, cousins and friends and was like a father to each of his children's friends. He was a loving father, grandfather, brother, uncle, great uncle, son, cousin and friend to many. He will be dearly missed.
