Stuart Lee Steinberg
Stuart Lee Steinberg
February 25, 1948 – October 21, 2026
Stuart Lee Steinberg was born in Titusville, Pennsylvania, to Flora and Max Steinberg. The third of four children, he learned early how to win over a full house. Charm became his first act, and it would be the first of many.
At Titusville High School, he ran track on a winning mile relay team and sang in the chorus. After serving in the U.S. Air Force from 1967 to 1971 as an X-ray technician with the 825th Medical Group in Little Rock, Arkansas, he followed his love of people into psychology, graduating from Allegheny College in 1975 and earning a master’s in clinical psychology from Edinboro University of Pennsylvania in 1977.
A licensed psychologist, he worked in hospitals, private practice, youth programming, and correctional facilities, ending his career as chief psychologist at SCI Mercer. His greatest joy was watching people feel capable, recover, and succeed.
Pittsburgh held a special place in his heart. He counted his decades there among his happiest, enjoying the Carnegie Science Center, Phipps Conservatory, Raccoon State Park, the Three Rivers Arts Festival, and Sundays cheering on the Steelers. There, he opened his private practice, S.L.S. Associates, and welcomed his beloved daughter, Haley, with her mother, Deborah Blair (Alabran).
Stuart loved beautiful cars, new places, and someone beside him to share the story. His most prized was his 2004 Jaguar XKR Portfolio in Jupiter Red Mica, customized with a supercharged engine and a “1 of 100” license plate. In 2023, it earned North American First in Class with a near-perfect score of 9.99967 out of 10.
A natural showman, he was a storyteller, actor, and singer who could fill any room with laughter. He performed in theater, wrote award-winning fiction for Jaguar publications, and served on the board of the Greenville Symphony Orchestra.
He collected lifelong friends everywhere, often popping by their homes unannounced with a little gift in hand. At home, he was a doting cat dad, never without a furry companion or two.
In his later years, Stuart shared a lakeside home in Chagrin Falls, Ohio, with his fiancée, Susie. With his siblings, Bob and Arlene, nearby, his days were filled with family, friends, kayaking, shared dinners, and long conversations.
His proudest role was father to Haley. He gave her his values, opened her mind to the world, and instilled the curiosity and care that guided his own life. Everyone could see how boundlessly he loved her.
Stuart faced cancer with fierce determination for the last twelve months of his life. Susie cared for him tenderly, and her love was a blessing to him and his family.
He passed peacefully on October 21, 2026, in Cleveland, at the Louis Stokes VA Medical Center’s Heroes Harbor, with Haley and her stepsister, Natalie Kazmierczak, by his side.
He is survived by his daughter, Haley, and her husband, Dave Santosuosso; his granddaughter, Sylvia Warren Santosuosso; his fiancée, Susie; his brother, Bob Steinberg, and Bob’s sons, David, Adam and Steven; his sister, Arlene, and her children, Amy and Glenn; his niece, Nina Huie, daughter of his late brother, Bryan; and many cousins and friends. He was preceded in death by his parents.
Friends and family are invited to celebrate Stuart’s life on Friday, November 6, at 1:00 p.m., at the Berkowitz-Kumin-Bookatz Memorial Chapel in Cleveland Heights, OH.
