Mary Elizabeth (Campbell) Steiner, age 84, wife of the late Otto K. Findeisen, of Royersford, passed away peacefully alongside family on May 28, 2025. Born May 20, 1941 at Hahnemann Hospital in Philadelphia, she was the daughter of the late Mary Elizabeth (Dolphin) and William James Campbell. Mary was raised in Mt Airy and graduated from Germantown High School in 1959 and Roxborough Memorial Hospital's 3 year RN program in 1962.

She worked at the operating rooms of Roxborough Memorial Hospital, Chestnut Hill Hospital and St Christopher's Hospital before taking a break and starting a family. She worked at local doctor's offices until starting at Phoenixville Hospital in 1977 where she worked for 27 years. In 1984, Mary became a CNOR. Mary's retirement didn't last long as she started work at the Limerick Surgery Center just 6 months later and retired in 2017.

Mary was a founding member of Freedom Lutheran Church and then attended Grace Lutheran Church. She was an avid bird watcher - traveling with Otto to watch birds was one of her favorite activities. She also enjoyed playing golf, first with Otto and later with many friends.

Mary is survived by her son, Ronald C. Yeager and his wife, Michelle; her daughter, Sharon L. Bittner and her husband, Brandon and her five grandchildren, Kyraen Bittner and her wife, Meredith, Ainsley Bittner, Teagan Bittner, Shaelyn Bittner and Gavin Yeager.
