Ossining, N.Y., March 13, 2026 ── Sister Patricia Gallogly, M.M., a Maryknoll sister of 75 years known for her adaptability and commitment to justice, died on March 1, 2026, surrounded by friends and staff at Maryknoll. She was 93 

Sr. Patricia was born on February 15, 1933, in the Bronx, New York, to Joseph and Rose O’Rourke Gallogly. Her parents and sister, Peg, predeceased her; she is survived by her sister, Kathleen.

Sr. Patricia was baptized at St. Jerome’s Parish, and received her high school diploma from the St. Simon Stock School. She would go on to complete her bachelor’s degree in education at the Maryknoll Teachers College in 1960, and attend the Pius X School of Liturgical Music at Manhattanville College.

In 1951, Sr. Patricia entered the Venard Maryknoll Society Community in Clarks Summit, Pa., after being inspired by stories in Maryknoll’s Field Afar Magazine. As she studied theology and missiology, Sr. Patricia’s spark for mission work grew into a flame — she received her first vows on March 7, 1954, and made her final vows six years later to the day, in 1960.

Sr. Patricia’s first mission took her to Africa in 1960, where she taught at the Makoko Girls Primary School for seven years. She also taught at the Musoma Junior High School Seminary for young boys in Tanzania, and at a girls’ high school in Machakos, Kenya. In 1980, she was called back to the Maryknoll Sister Center in Ossining, N.Y., to serve as the orientation director. Sr. Patricia returned to Tanzania once again to serve in the village of Kung’ombe, Bunda, where she taught local women how to knit and sew, while discussing women’s rights with them. She also worked as a health promoter, organizing support groups and trainings amid the HIV/AIDS epidemic in the Msang village and Mwanza. During this process, Sr. Patricia helped develop the Uzima Wellness Center in 2004, where women received medical assistance.

In 2007, Sr. Patricia was called to the Eastern U.S. Region, where she continued her ministry of justice and peace in Yonkers, N.Y. She later became the representative for the Faith and Justice Network in Washington, D.C. From 2017 until 2020, Sr. Patricia served as representative to the Maryknoll Affiliates and Full Circle.

Sr. Patricia returned to the Center in 2019, where she spent time writing about her experiences in mission and keeping in touch with her many friends from Tanzania, until she passed.

A wake for Sr. Patricia was held on March 10, 2026, in the Annunciation Chapel of the Maryknoll Sisters Center in Ossining, N.Y. A memorial Mass was said on March 11, 2026, also in the Annunciation Chapel.
