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.
