The Rev. Barbara Tobin, Deacon

On the first Sunday of Advent 2017, we welcomed the Rev. Barbara Tobin to St. Mary’s as our vocational deacon. Barbara is a longtime member of St. Peter’s in Old City, and after she retired as a Palliative Care Nurse Practitioner in 2013, she had a year’s Sabbatical, then felt called to the Diaconate. She was ordained in June 2016 and had served at St. Simon the Cyrenian Church. Deacon Barbara will serve on an annual basis in the parish with the permission of our bishop, with a particular focus on connecting the parish to the needs of the poor and homeless in our city. She is looking forward to ministering with everyone at St. Mary’s in living out our Baptismal vows together. Have questions about what the vocational diaconate is? Ask away!
