Susan W. Mangam, 86, of Tannersville, passed away at her home on July 14, 2023. She was born on May 30, 1937 in Mineola, NY to the late Elliott W. and Winifred (Pfordte) Mangam. Raised in Fall River and Fitchburg, MA, she graduated from Fitchburg MA High School in 1955. She graduated with an A.B. in Arts from the University of New Hampshire in 1959 where she was the first violinist of the university orchestra. Later she attended Yale University, graduating in 1962 with a Bachelor and Masters in Fine Arts. She then accepted a teaching position in 1962 at Mt. Holyoke College, South Hadley, MA as an Instructor of Art, later being elevated to a fully tenured Professor. While there, she participated in the 3rd civil rights march from Selma to Montgomery, AL in March 1965 – having helped organize a group of students and faculty. She left Mt. Holyoke in 1975 to support the Episcopal Church of America and pursue her passion to help and serve others, first in Springfield, MA and then in locations in the Eastern US, Canada and Texas. She moved to Tannersville in 1979 and become a solemnly professed religious solitary as (Sister) Susan John in 1985. Susan was a devoted environmentalist, a spiritual director, and friend to many. She was under the direction of the Bishop of Maine and maintained her official membership at St. Brendan the Navigator in Deer Isle, ME. Susan was deeply involved at Gloria Dei Episcopal Church, Palenville where she attended Sunday services most of the year. She also participated in activities at Holy Cross Monastery (Hyde Park) and the Companions of Mary (Magdalene), also in Hyde Park. Among her other passions were tending to her gardens (flower and vegetable), her early morning nature walks, her pets, and travelling to Little Deer Isle, ME. She also enjoyed traveling to the Isle of Iona, Scotland for an annual religious retreat. Susan was an accomplished artist. She painted landscapes in acrylic of the Catskills as well as the Maine and Scottish coasts — images of inspiration and spirit involving the intersection of sky and water. Susan was pre-deceased by her brother-in-law and sister, Jack and Barbara Worth of Tannersville, her niece, Lauriann Worth, and Karl Pfordte (a cousin). She is survived by two nephews, Mike Worth of Mt Laurel, NJ and Joe (Laurie) Worth of Tannersville, and two cousins, Mary Jane Pfordte and Carol Mabin (Keyle). A memorial service will be held on August 29th at 2pm at Gloria Dei Episcopal Church, Palenville.
