Rev. Sophia M. Lyons, Minister


Rev. Sophia joyfully accepted the call to serve as the 30th settled minister at First Parish of Watertown in May of 2021 and considers it a great honor to minister to this beautiful community. She received her Master of Divinity from Boston University’s School of Theology in 2019 and was ordained by the First Religious Society UU of Newburyport, MA in 2021. Before coming to FPW, Rev. Sophia served as Intern and Sabbatical Minister at the UU Church of Haverhill, MA, year-round Island Minister on Star Island, and Memory Care Chaplain at Hebrew Senior Life in Dedham, MA. She also holds a BA in Education having taught high school English for a stint, spent many years in the theater performing in Chicago and Los Angeles, was a public relations executive, as well as a natural childbirth instructor! The path to ministry was most certainly a winding one…

Raised in Los Angeles, CA, Rev. Sophia moved to New England in 2011, having lived in Chicago, IL and Portland, OR for a long while in between. She lives in Watertown with her husband, Jason, and two daughters, Olive and Poppy. Rev. Sophia enjoys yoga, music (particularly the kind you can dance to), communing with Nature, and taking orders from her lop-eared rabbit and tuxedo cat.

Rev. Sophia is committed to radical welcome and spreading the good news that is our bold Unitarian Universalist faith. Some of her areas of interest include interfaith partnerships, spiritual formation and direction, and working towards collective liberation for all. Rev. Sophia aspires to live her life and fulfill her ministry guided by spiritual seeking, an ethic of love, and the guiding principles and theology of Unitarian Universalism.

Rev. Sophia is generally at church Tuesdays, Wednesdays and Thursdays. Mondays are her Sabbath days, where she rests, and Fridays are her sermon writing days. You can email her at or leave her a voice message at 617-744-0913 to schedule a meeting.
