Dianne Elizabeth Kosa

Dianne Elizabeth Kosa, of Milford, passed away peacefully surrounded by her family on December 29th, 2025. She was the beloved wife of the late Edward Kosa and cherished mother and nana to her children, grandchildren and great-grandchildren.

Dianne was born on January 15, 1945, in Milford to the late Michael and Edna Surenko. She grew up in Walnut Beach, where her father owned the well-known Spike’s Diner. For most of her life, Dianne worked at Warners in Stratford and later spent a decade working at Subway World Headquarters, from which she retired.

Dianne enjoyed listening to music, reading a good book at the beach, cooking, and spending cherished time with her family. She loved taking day trips to Mohegan Sun with her girlfriends and had a youthful spirit—always keeping up with the latest streaming shows and pop-culture gossip. And if you asked any of her grandchildren, they would tell you she made a stellar egg sandwich.

Dianne’s legacy lives on through her family: her children, Bruce Kosa and his wife Deborah of Cheshire; Kathy Taylor and her husband Billy of Mississippi; and Edward Kosa and his wife Rebecca of South Windham. She is also survived by her grandchildren, Joseph Dickson and his husband Victor, Nicholas Kosa, Kristen Hale, Brittany Hale, Don Piche, Alyssa, Joseph, and Dennis; her great-grandchildren, James, Remiel, Aniyah, Jayda, and Zariah; and her brother, Michael Surenko, Jr.

In addition to her husband and parents, Dianne was predeceased by her granddaughter, Patrice Kosa; her brother, Richard Surenko; and her sister, Gloria Haray.

Family and friends are invited to pay their respects from 10:00 a.m. to 12:00 p.m. on Tuesday, January 6, at the Gregory F. Doyle Funeral Home, 291 Bridgeport Avenue, Milford. A graveside service will follow at 12:30 p.m. at Kings Highway Cemetery in Milford.
