Thomas “Tom” Mizonick, 90, passed away peacefully on March 2nd, 2026, in Santa Clarita, California after a lengthy illness. He was born on September 23rd, 1935, a beloved son of the late Michael Mizonick and Helen Puchar Mizonick. In addition to his parents, he was preceded in death by his devoted wife of 63 years, Betty Fischer Mizonick, his son-in-law, Jan Prasniewski, his brothers: John Sonich, Charles Sonich, Stephen Locke, and Nick Locke and his sisters, Anne Havis and Kathryn Nedde. Their memories remained a source of strength and comfort throughout his life. He is survived by his loving daughter, Lisa Mizonick of Santa Clarita, California, who was his constant support and devoted caregiver, his nephew, Richard Locke of Plano, Texas, his sister-in-law, Sally Kuhel and her husband, Rudy of Ambridge, and many cherished nieces and nephews who treasured his warmth, humor, and gentle presence.

Thomas was raised in a close-knit family and his values of kindness, loyalty, and generosity shaped the steady and compassionate man he became. He was a man of quiet resilience and deep loyalty and he leaves behind a legacy of kindness, family devotion, and unwavering love. His absence will be deeply felt, but his memory will continue to bring comfort and gratitude to all who knew him. He was an avid golfer and football fan, passions that brought joy and camaraderie throughout his life. He proudly served in the U.S. Army and retired after a lengthy career at the Motion Picture Industry in Studio City, California. He was also a 1954 graduate of Ambridge High School and he valued lifelong friendships, including his friend Rich Vasques.

A memorial service will be held at a later date in California to celebrate his life and legacy. Arrangements have been entrusted to the John Syka Funeral Home, Inc., 833 Kennedy Drive, Ambridge.
