Irene C Dinerstein

Irene Carol Dinerstein, 83, of Commack, New York, passed away peacefully on Monday, April 16, 2026, surrounded by her loving daughters, after an extended illness. Barely a week earlier, Irene celebrated her birthday with family and friends—an occasion filled with the warmth, laughter, and connection that defined her life.

Born in Brooklyn, New York on April 5, 1943, Irene lived a life rooted in purpose, generosity, and deep human connection. She was known above all for her unwavering belief that small acts of kindness could ripple outward in meaningful ways. Her motto was, “As one person I cannot change the world, but I can change the world of one person.” And she did—again and again.

Irene was the beloved wife of Robert Jay Dinerstein (Bobby), who predeceased her, and a deeply dedicated mother to her two daughters, Alicia Dinerstein and Elena Brezina—who were frequently told by Irene and others just how extraordinary they are. She cherished her “grand dogs”—Sophie, Oliver, Lucy, and Oreo—showering them with affection and treats, and delighting in endless videos of dogs doing sweet and silly things. She especially loved dog movies—whether they made her laugh out loud or brought tears to her eyes.

To many, Irene was best known as the legendary “giraffe lady.” Her extraordinary collection of giraffes earned her a place in the Guinness Book of World Records, but more importantly, it became a joyful mission. Irene carried small giraffes with her wherever she went, gifting them freely—to delivery workers, plumbers, medical staff, students, and strangers alike. People who crossed her path often left with a giraffe and a smile. Sharing that joy brought her immeasurable happiness.

Professionally, Irene devoted 40+ years as a social studies permanent substitute teacher at Commack High School, where she was cherished by generations of students. She inspired curiosity not only in the classroom but also through engaging presentations about her adventures in China, Nepal, Thailand, and other destinations. She was also immensely proud of leading the student group “Grandfriends,” fostering meaningful connections between students and seniors—and becoming a surrogate grandmother figure herself to many of her students.

Irene was remarkably social, forming deep and lasting friendships across generations and circles—from “the Groupies” to the “Golden Girls” to the “Silver Girls” to her Chinese ‘grandchild,’ Melody—and many more. She had a gift for making people feel seen, valued, and included.

Her passion for politics was equally strong. Irene stayed engaged, vocal, and active—whether attending rallies or passionately reacting to the news from her living room, often loudly and unapologetically, even from a wheelchair when necessary. Her voice and spirit were never diminished.

Above all, Irene lived with heart, humor, and an irrepressible desire to connect. Her legacy is one of kindness, laughter, and the countless lives she touched in ways both big and small.
