Rev. Tom O'Brien
Senior Pastor and Teacher
Pastor Tom (he/him) has been with us since 2010. Originally from New York, Tom moved to Massachusetts in 1996 to be with his love, Rachel, whom he married in 2001. Raised Roman Catholic, they discovered the United Church of Christ after their first child was born. After a short time attending worship services, Tom heard a call to the ministry and entered Andover Newton Theological School where he received a Master of Divinity with a focus on Worship, Theology, and the Arts. He seeks to help others recognize the awesome hope in the good news of Jesus Christ and to follow in Christ's footsteps, working towards a radically inclusive world that mirrors God's love for all Creation "on Earth as in Heaven."

Samuel Long
Director of the Senior Choir and Worship Accompanist
A native of Rutland, MA, Sam grew up singing in a handful of church choirs in Worcester before enrolling in the St. Thomas Choir School in New York City at the age of 10. He attributes his passion for liturgical music to the 4 years he spent singing 5 weekly church services at St. Thomas under the direction of Dr. John Scott. Later on, during his first year at Phillips Exeter Academy in New Hampshire, Sam started studying organ with a handful of organists through local Churches and an AGO Pipe Organ Encounter. Sam recently graduated from St. Olaf College with a B. M. in Church Music and Organ Performance and has most recently been living in Atlanta, working as an Organ Scholar and Minister of Music at Redeemer Lutheran Church and St. Andrew’s Episcopal Church respectively. When Sam is away from the organ bench, he can often be found going for long runs and hikes.
