Dennis O'Connor May 20, 1936 to December3, 2016
Dennis was born in the Bronx, New York and graduated with a bachelor's degree from Iona College. He had a distinguished career in the packaging industry, working for several major companies, retiring in 1999. This was, however, just what he did, and was not who he was.

Dennis was a man of intellect and integrity, whose love of family defined him. He is survived by his wife of 57 years, Carole, with whom he raised a family in Mahopac, New York. He is further survived by a son Richard, and daughter Lynda, along with six grandchildren; Kathryn, Patrick, and Kevin O'Connor; Shaylyn, Annalyse, and Seth Lyons. Family was his touchstone and the partnership he had with his wife and was considered special by all who knew them. As a father, he was the ultimate teaching mentor for his children leading and directing by example. He was supportive and dedicated to his children. From spending many freezing cold nights attending Richard's hockey games, sipping coffee from his thermos, to helping Lynda nurse a stray animal back to health, Dennis supported and cultivated each of his children's interests. His six grandchildren also benefitted, nurtured by his love, guidance, and example for decades. He will be sorely missed by the entire family.

Dennis was extremely intelligent and was a voracious reader of a diverse genre of literature. The family affectionately referred to him as the "book of knowledge" and one did not relish playing him in a game of trivial pursuit. He was insightful and had a remarkable sense of humor, no doubt emanating from his Irish roots, of which he was very proud. His trips to Ireland with family were highlights for him.

Dennis was a lover of animals of all kind, but particularly dogs. Rusty, Cody and the other family member dogs all benefitted from this love. All dogs readily identified Dennis as the "dog person" in the room to whom they reliably would receive treats. He also fed the birds in his yard on a regular basis and took in stray cats that found their way to his door. All animals instinctively recognized that Dennis was there to help them.

Dennis had varied interests, including cars and car restoration. He further made many model airplanes that were unique in their craftsmanship. Later on in his life Dennis became involved in his church.

Throughout his life, Dennis had health challenges, most notably kidney disease. Dennis fought this chronic disease stoically and with dignity.

Dennis O'Connor was a special man who has left his footprint on the world around him. It was truly a life well lived and he will be sorely missed by all that knew and loved him.
