Patricia "Pat" A. Coller, 85, died peacefully in her sleep on September 26, 2025, in Lancaster, Pennsylvania.

Born in Lancaster on September 17, 1940, she attended St Anthony Catholic School and graduated from Lancaster Catholic High School in 1958. She began her career as a lab technician at St. Joseph Hospital, then spent 22 years in the Product Styling and Design Department at Armstrong World Industries. After retiring from Armstrong, she worked as a constituent service assistant for Representative Mike Sturla and later as a receptionist for Mid-Atlantic Psychiatric Physicians.

A lifelong public servant, Pat volunteered tirelessly for the City of Lancaster. She served on numerous boards and commissions and was a Lancaster City Council member from 2008 to 2011. For 20 years she was an interpreter and tour guide for the Historic Lancaster Walking Tour, delighting in sharing the city's distinctive architecture. She also worked closely with local neighborhood groups such as the Positive Image Action Group. A proud Democrat, Pat was an active committee person for many years. She was active in the Lancaster Downtowners organization and cherished the time spent with the "Bocce Babes." Strolling through Lancaster with her meant constant greetings from the many people who knew and loved her.

Pat cherished her family above all. She was the devoted mother of Chris and the late Theresa Coller and especially proud of her grandsons, Sean and Ryan. Known as the "glue" of the family after her mother's passing, Pat hosted large Thanksgiving gatherings, often welcoming friends and neighbors who needed a place to belong and a home cooked meal. She had a quick wit, a love of travel, and a fearless appetite for new adventures well into her seventies.

Pat was preceded in death by her parents, Marie Tolland Reusing and Albert M. Reusing; brothers Michael P., Albert M., and Vincent P. Reusing; and her beloved daughter, Theresa M. Coller.

She is survived by her son Chris Coller and his wife Teresa; grandsons Sean and Ryan Coller; brother Tim Reusing and his wife Emily; sisters-in-law Kathe Cotton Reusing, Pam Johnston Reusing, and Donna Reusing; and many cherished nieces and nephews across the country.

A memorial service will be held at Charles F. Snyder Funeral Home & Crematory, 414 E. King Street, Lancaster, PA 17602 on Saturday, November 15, 2025. Visitation begins at 10:00 a.m., followed by a service at 10:30 a.m. A private family interment will take place at St. Joseph's New Catholic Cemetery.
