Mr. David H Quadrato

June 7, 1949 — April 11, 2023

“Local Tax Preparer and devoted family man”

OAKVILLE – David H. Quadrato, age 73, of Oakville passed away peacefully at Waterbury Hospital on Tuesday April 11, 2023 after an extended illness. He was the husband of the late Kathleen (Butler) Quadrato.

Dave was born June 7, 1949 in Waterbury, CT, the son of the late Frank and Betty Jane (Bradshaw) Quadrato. He was a graduate of the Watertown High School class of 1967 and a well-known member of the community as an accountant providing income tax preparation and filing services as well as bookkeeping to a plethora of people and businesses in town and around the state. Dave was a true “workaholic” making sure that all of his client’s needs were tended to at all times. If he wasn’t busy working, he would enjoy taking time to watch a Red Sox game or taking a trip to the casinos. Dave was exceptional in almost every way, but he excelled the most at being a devoted husband, father, grandfather and great-grandfather. His family was his priority throughout his life however, he worked hard, even until his final days, to try to provide for them. He will leave a noticeable emptiness in the lives of his family, clients and all who simply knew him from “around town”.

Dave was predeceased by his wife and soul mate, Kathleen (Butler) Quadrato, his brothers, Frank Quadrato, and twins Gary and Glen Quadrato. He leaves behind a large family to grieve his passing, honor his legacy and cherish his memory, including his three sons, David H.
