Since the age of 12, Garrett has developed his passion and talent for liturgical music. Currently, he serves as Assistant Organist and Cantor at the historic Roman Catholic Parish of Saint Stephen in Ohio City and Organist-Choirmaster and Director of Music at St. James Anglican Catholic Church in Downtown Cleveland. The St. James Choir is an ensemble of eight voices which offers a choral setting of the Ordinary of the Mass and chanted Minor Propers for every Sung Mass, along with occasional motets. Its repertoire ranges from Gregorian Chant and Renaissance Polyphony, masses from Haydn to Howells, and commissions by local composers. In March 2017 Garrett conducted the St. James Choir and chamber orchestra in a performance Faure's Requiem.
Before St. James, Garrett previously served as Assistant Organist-Choirmaster at St. Paul's Episcopal Church in Akron, Ohio from 2013-2016. While in Akron he developed an affinity for the anglican organ and choral tradition under his personal mentor and Organist-Choirmaster, Daniel Fortune. Garrett enjoyed working in a parish with a large volunteer music program made up of three choirs: The Choir of Men and Boys, The St. Cecilia Choir of Girls, and The St. Catherine's Choir of Women. St. Paul's is a member of the Royal School of Church Music and Garrett found the training of young choristers in musicianship and vocal technique to be extremely rewarding. In 2014, the choirs of St. Paul's completed a choral residency at Ely Cathedral. Garrett performed voluntaries in the Cathedral and accompanied choral evensong in the Lady Chapel of Ely Cathedral.
In the summer of 2015, Garrett studied with Tom Bell and Daniel Moult at Oxford University as part of "The Organ Scholar Experience", the Royal College of Organists flagship program for young organists. He also has attended choral conducting seminars at Westminster Choir College, where he received intensive instruction from James Jordan. In addition to multiple AGO national and regional Conventions, Garrett attended the Sewanee Church Music Conference in 2014.
