Diane Costanzo, a longtime resident of Barton, died on July 3, 2026, at her home.  Diane enjoyed the quiet and beauty of the Northeast Kingdom.

Born in New York on May 9, 1955, to Joan Leaman Costanzo, Diane relocated to Ridgewood, New Jersey, with her mother, in the early 1960s where she was later joined by her sister Virginia (Ginny) Adler, and brother Geoff Adler.

Diane completed her education at Ridgewood High School in 1972 and subsequently obtained a BS in physical education from Lyndon State College in 1976.  As an outstanding goalie for the women's "Hornets" field hockey team, she was renowned for her exceptional defense, particularly her remarkable performance against Castleton State during the 1974-1975 season.

Following college, Diane held various positions, including roles in teaching physical education, construction, prison security, and factories, such as the Ethan Allen furniture mill.

Diane had a tight-knit circle of friends, with Marlene being one of her closest. Marlene's passing a few years back left a profound sorrow.

Her greatest affection was reserved for her animals, especially her dogs and cats, who brought her immense joy and solace.

Diane is survived by her half-brother Geoff Adler; her nieces Christine, Adriana, Ella, Caitlyn, and Hannah, her nephew Max; and her step-brother Rick Adler.  She was also predeceased by her mother Joan Adler, stepfather Allen Adler, half-sister Virginia (Ginny) Greene, and step-brother Robert Adler.
