Maureen retired as a Project Coordinator from Education Development Center, formerly employed by Digital Equipment Corporation, but most loved her years teaching Kindergarten and 2nd grade in the Concord and Acton, MA, school systems. She was a member of the Liberty Belle Chorus of Sweet Adelines, formerly in Arlington, MA, for 25 years.

She filled her life in retirement with many hobbies centered around community and joyful togetherness. She cuddled babies in the Tufts Hospital NICU, volunteered at MANNA for the homeless at St. Paul’s Cathedral in Boston, visited detainees in the detention center at Suffolk Jail, was an election poll worker for many years and strongly believed in participatory democracy. Maureen was an active member of St. John’s Episcopal Church in Charlestown and also the Charlestown Lions Club. Her joy was spending time with family and friends; her interests were reading, walking, activities in the city, swimming, singing, and traveling; and her passion was for justice and peace for all.

A memorial service will be scheduled at a later time. In lieu of flowers, the family requests donations to The Greater Boston Food Bank or local community charity of your choice.

May her generous spirit, warm heart, and boundless love live on in all who were blessed to know her.
