Patricia A. "Trish" Marcilliott, 52, of Niagara Falls, NY, passed away peacefully on December 8, 2025, at home under the loving care of Niagara Hospice. Born in Dunkirk, NY, she was the beloved daughter of Diane (Lentz) Marcilliott and the late Richard Marcilliott.

Trish moved to Niagara Falls as a child with her family and graduated from Niagara-Wheatfield High School. For many years, she was employed at the 914th Airlift Wing of the U.S. Air Force Reserve in Niagara Falls, a position she truly loved.

Trish found joy in camping, especially at Niagara Hartland Resort in Gasport, NY, where she shared countless memories with friends and family. She was a proud season ticket holder and devoted fan of the Buffalo Bandits, and she had a deep love for animals, especially dogs. Above all, she cherished time spent with her family.

In addition to her mom, Diane, she is survived by her sister, Michelle Marcilliott; her brother, John (Caroline) Marcilliott; her nieces and nephew, Alicia, Jonathan, and Faith; as well as many aunts, uncles, and cousins. Trish will also be deeply missed but never forgotten by her 914 Family and her camping family at Niagara Hartland.

Visitation will be held on Friday, December 12, from 3–8 PM at M.J. Colucci & Son Niagara Funeral Chapel, 2730 Military Road, Niagara Falls, NY 14304. Trish's Mass of Christian Burial will be celebrated on Saturday, December 13 at 10:00 AM in St. Leo's Church, 2748 Military Road, Niagara Falls, NY 14304.
