In the quiet hours of April 3, 2025, Kristin Beth DiMuzio slipped away peacefully at UPMC Montefiore in Pittsburgh, Pennsylvania, cradled by the love of her family. Her passing marked the end of a valiant struggle against Moyamoya disease, a rare and progressive condition that narrows the arteries at the base of the brain, often leading to strokes and other complications. Surrounded by those who mattered most to her, Kristin left behind a legacy that resonated far beyond the confines of her Moon Township home. She was 38 years old, a devoted wife to Luke DiMuzio, and a doting mother to their two young children, James, 10, and Anna, 7. Her death has left a void in her family and community, but her life—marked by resilience, compassion, and an unyielding commitment to others—continues to shine as a beacon of inspiration.
Kristin’s journey with Moyamoya disease was one of quiet bravery. Diagnosed several years ago, she faced the uncertainty of her condition with grace, undergoing multiple surgeries to restore blood flow to her brain. Despite the physical toll, she refused to let the illness define her. Instead, she poured her energy into the things that mattered most: her family and her community. Luke, her husband of 14 years, described her as the heart of their household, a woman whose strength held them together even in the darkest moments. “She never stopped fighting,” he said in a statement released by the family. “Not for herself, but for us—for James and Anna, for everyone she loved.” Her children, who were her greatest joy, often spoke of their mother’s ability to make every day special, whether through a bedtime story or a spontaneous trip to the park.
Beyond her family, Kristin was a pillar in Moon Township, a tight-knit community just west of Pittsburgh. She was a familiar face at her children’s schools, volunteering countless hours to organize fundraisers, chaperone field trips, and support teachers. Her warmth and reliability made her a trusted friend to many parents and educators alike. But perhaps her most enduring contribution was her work with the Make-A-Wish Foundation. Kristin’s involvement began shortly after her diagnosis, when she learned of the organization’s mission to grant wishes to children with critical illnesses. Drawn to the cause, she became a tireless advocate, helping to plan events and raise funds to bring joy to families facing challenges similar to her own. Her efforts touched dozens of lives, including those of children who, thanks to her, experienced moments of happiness amid their struggles.
Born and raised in Pennsylvania, Kristin graduated from Moon Area High School before earning a degree in education from Slippery Rock University. She met Luke while working as a teacher’s aide, and their shared passion for helping others quickly blossomed into a deep partnership. After their marriage in 2011, they settled in Moon Township, where they built a life centered on family and service. Even as her health declined, Kristin remained active, attending community events and cheering at her children’s soccer games whenever she could. Her determination to live fully, despite her illness, left an indelible mark on those around her.

final years. First identified in Japan in the 1960s, the condition remains poorly understood, and treatment options are limited. For Kristin, it meant a series of complex surgeries at UPMC Montefiore, a leading medical center known for its expertise in neurosurgery. The hospital staff, who cared for her over multiple admissions, remembered her as a patient who faced each challenge with dignity and a smile. Her medical team noted that her positive attitude not only buoyed her own spirits but also uplifted those around her, from fellow patients to the nurses who became like family.
Kristin’s passing has elicited an outpouring of grief and gratitude from her community. Friends and neighbors have flooded social media with tributes, recalling her infectious laugh, her homemade cookies at school bake sales, and her knack for making everyone feel seen and valued. The Make-A-Wish Foundation of Greater Pennsylvania and West Virginia issued a statement honoring her contributions, noting that her dedication helped grant wishes to more than 20 children in the region. Plans are underway for a memorial event to celebrate her life, with proceeds benefiting the organization she held dear.
As Moon Township mourns, Kristin Beth DiMuzio’s story stands as a testament to the power of love and resilience. Her legacy lives on in her children, who inherit her kindness; in her husband, who vows to carry forward her spirit; and in a community forever changed by her presence. Services will be held later this week at St. Paul’s Lutheran Church, where Kristin was a longtime member, followed by a private burial. In lieu of flowers, the family requests donations to the Make-A-Wish Foundation, ensuring that Kristin’s light continues to shine for others.
