Dennis J. Kerwin, 65, of Old Lyme, CT passed away at home on Tuesday, September 15, 2020, surrounded by his loving family after a courageous battle with cancer. He was born on April 14, 1955 in Hartford. He was the son of the late James T. Kerwin and Irene B. Kerwin. He attended The Robinson School and graduated in 1974, and completed some college education at Dean Junior College. He worked alongside his father in the construction industry and eventually started his own business, Kerwin Construction Services in the late 1980’s. He was an extremely hard worker and had experience in all aspects of construction. His true passion was sport fishing and boating, having built and owned many over the years. He lived and died by the sea. He took numerous trips up and down the East Coast from Nova Scotia to Key West in pursuit of his love of boating. He spent many summers at White Sands Beach growing up, and always enjoyed being on the water or near the water. He enjoyed spending time at Martha’s Vineyard and more recently, Block Island. His greatest qualities were his sense of humor, his gift of gab, and his generosity. He was an adoring father, softball and basketball coach, and avid sports enthusiast. He attended several Daytona 500 races, and was formerly a Giants fan until the Patriots came to Foxboro. He is survived by his loving wife Karen and son James Kerwin of Old Lyme, CT, daughter, Marissa Carignan and her husband Blair, and precious granddaughter Sloane of Waterford, CT; sisters, Jeanne LeBlanc of Enfield, CT, Kathy Cox and her husband James of Enfield, CT, and Maureen Domenicone and her husband David of Wellesley, MA; aunt, Joanne Beard of Enfield, CT; nieces and nephews, Brittany, Jenna, and Alexia Cox, Matthew and David LeBlanc, and Mila and Cooper Domenicone.

Dear Karen, Marissa, and families, I was so sad to see this news. While I didn't have much interaction with Dennis as you girls went through school together, the last time I saw him was a few years ago at the Sound View gas station, where we were filling our cars at adjacent pumps. We said hello, and then he started telling me all about your recent wedding, Marissa--what a proud Dad he was following what must've been a beautiful event! And he must've been over the moon to have a granddaughter! I am very sorry for your loss. Michele Dickey
