Diana Lee Stelluto (Clark)

Diana Lee (Clark) Stelluto, 82, of Pittsburgh, passed away peacefully on July 5, 2026, surrounded by her family and friends.

Born on November 30, 1943 to Wilbur and Emma Clark, Diana dedicated 38 years to teaching in the Shaler Area School District, where she inspired generations of students with her kindness, patience and sense of humor. Her core values centered around feminism, equality, and independence, and she believed that a solid educational foundation was essential for everyone. While she took great pride in her career, the greatest joy and proudest accomplishment of her life was her daughter, Leanne. She loved every moment spent with her daughter and found endless happiness in her grandsons, Jules and Ellis, who brought immeasurable love and laughter to her life.

Diana is survived by her daughter, Leanne (Ross) Andrysco; her grandsons, Jules and Ellis; her sister, her nieces, Julie (Steve) and Jennifer (Nate) and their children, whom she loved dearly. She will also be deeply missed by her many wonderful friends and neighbors. 

Family and friends will gather privately to celebrate Diana's life and honor her memory.

In lieu of flowers, memorial donations may be made in Diana's memory to the Humane Animal Rescue of Pittsburgh at humaneanimalrescue.org/donate/ or the Greater Pittsburgh Community Food Bank at pittsburghfoodbank.org
