It is with great sadness that the family of William Joseph Colantonio announce his peaceful passing at the age of 69, after a long and courageous battle with cancer.  In his lifetime, William made deep ties in many places, including Dorchester, Quincy, South Boston, Wareham, and most recently Raynham.

William is survived by his loving mother, Marie J. “Nana” Colantonio. She shared a special bond with her first child and was by his side through his life, through his illness, and in his passing.

He was the son of the late Domenic “Sonny” Colantonio. 

William was the loving father of Derek Colantonio of West Virginia, Matthew Colantonio and his wife Jessica of Quincy, Ami Draheim and her husband Jay of Texas, Carly Colantonio of Quincy, and Paige Colantonio of Wareham. His children will remember the many laughs they had with their Dad and the steadfast love and pride he had for them.  

He was a devoted brother to his sisters Joanne Colantonio of Roslindale, Linda Conroy of Taunton, and Marie Milano and her husband Sonny of Raynham. William will be reunited in Heaven with his younger brother, Michael A. Colantonio of South Boston.

He was the proud Pappy of Madison, Matthew, Caroline, Annie, Michael, William, Charlie, Molly, Libby, Lilah, Owen, and Joseph. His grandchildren remember their fun-loving Pappy for spoiling them with treats and good times.

He was an amazing uncle to his niece, Payton Colantonio, and nephews, Michael Conroy and Taylor Colantonio.

William loved many things in life. He was an avid sports fan, especially of boxing and the Boston Bruins. He loved music and found life’s meaning in the lyrics to his favorite songs. If you knew him, he probably sanded your floors at some point. He always had some project going on and often left them unfinished. He loved root beer floats and was an amazing cook. He was at his happiest when he was making a nice meal for those he loved.
