After Miller graduated from Wellesley College in 1966, she spent several years as a stay-at-home mother, worked as an accountant, and became an activist for teenage mothers. She then studied at Reconstructionist Rabbinical College and was ordained in 1986. She began serving as a rabbi at Adas Israel in Washington, DC while still a rabbinical student, and remained with the congregation for her entire career, becoming rabbi emerita in 2008. While there, she created learner’s minyans and founded Open Dor, a foundation to engage and serve unaffiliated Jews. She also led the synagogue in an influential campaign to aid Ethiopian Jews and published a collection of sermons, On the Wings of Hope, in 2002. Her focus on outreach also guided her work for the Rabbinical Assembly, the professional organization of Conservative rabbis, as a regional president, member of the executive council, and leader of the RA’s national outreach and conversion committee.
