Sister Marguerite Buchanan, RSM

Sister Marguerite Buchanan died May 26, 2021, at Marian Oaks Care Center in Burlingame. Born in 1932 in Berkeley, CA to Duncan and Margaret Dunne Buchanan, and named Barbara, she graduated from Holy Names High School and enrolled at St. Mary's Hospital School of Nursing in San Francisco. It was there she met the Sisters of Mercy and entered the community in Burlingame in 1951. She received the religious name of Sister Mary Marguerite and professed first vows in 1953.

Sister Marguerite completed a BA degree at USF and earned MA degrees in physics and in Educational Administration. She taught science and religion at Mercy High School in San Francisco and later at Mercy in Burlingame. She also served as principal and then as development director in each of these schools.

In 1985 she completed training in spiritual direction, and then earned an MA in transpersonal psychology. She served on the staff of Mercy Center from 1985 – 2003.

Leading centering prayer at San Quentin Prison and the Federal Correctional Institution for Women made her aware of challenges women face following time in prison and inspired a new work. In 2003 in collaboration with the St. Vincent de Paul Society, she opened Catherine Center, a live-in program providing integrated services to post-incarcerated women. She was administrator there until 2011, and continued to play a significant role until her death. Her passion for justice never waned; she also stayed involved in a number of local ministries and encouraged others to do the same.

Sister Marguerite will be remembered for her joyful spirit, compassion, creative planning skills and ability to delegate and involve others in her good works.

She is preceded in death by her brothers Duncan and David and survived by her nephew Paul (Penny), and nieces Mary, Katie (Jason), and Peggy (George), other loving relatives, friends, and her community of Sisters of Mercy.

I was introduced to Sis. Marguerite through Catherine Center. She reminded me that I was a Child of God, and that my past did not define me. She encouraged me to reconnect to my faith so that I could serve God and draw closer to him. She shared that with me when I believed "God hated me". Her life showed me the love that God has for me. Sister Marguerite THANK YOU, may you rest in peace

Sister Marguerite was my favorite Sister during my four years at Mercy High. I remember sitting and learning in both her biology and physics classes. In fact, it was her superb ability to teach and communicate that influenced my decision to become an RN. At our 55th class reunion, I was able to thank her personally for what she did for me not only as a nurse but also as a woman. May Sister Marguerite rest in eternal peace and joy.

As my Mercy High School principal, I always felt that Sr. Marguerite was a fair and approachable woman and person of authority. I am sorry to know she is now gone. With respect and condolences, Cindy (Casey) Franco, Class of 1975
