Dennis D.M. O'Brien Obituary
We are sad to announce that on March 19, 2021 we had to say goodbye to Dennis D. M. O'Brien of Mystic, Connecticut, born in Tucson, Arizona. You can send your sympathy in the guestbook provided and share it with the family.
He was loved and cherished by many people including: his parents, Abby O'Brien and MJ O'Brien; his wife Debby; his sons, James (Tim) and James' (Lauren); his brother Tim; his sister-in-law Nadine; his aunts, Joan and Jane; and also Anne.
In lieu of flowers, the family asks that you consider making a donation to the Denison Pequotsepos Nature Center, Pine Point School, or the Mystic Museum of Art.
