Organist

Jenny Yun began playing piano at age five. She credits her pianist mother for the early start. One of her proudest moments came at age fourteen when she performed Mozart Piano Concerto No. 26 in D major with the Korean Symphony. She went on to study Music Composition and Theory at Seoul National University, where she began to appreciate a broad range of musical compositions and their impact. Jenny’s passion for pipe organ began at the University of Kansas where she received her M.A. in Organ Performance. She has studied under renowned teachers Dr. James Higdon at the University of Kansas and Dr. Thomas Ladd of the University of Southern California. Her many years of experience as organist at Lutheran and Episcopal Churches left her with a deep understanding of Congregational Hymns and Liturgy and allowed her to appreciate the music of J.S. Bach and Brahms even more. She is a busy and proud mom of three daughters, Emily, Claire, and Grace.

Parish Choir Section Leaders

St. Bartholomew’s is privileged to have professional section leaders serve in each vocal part within the parish choir. From the greater San Diego community, they are teachers and mentors, singers and students; they serve as soloists as needed, help shape the sound of their section, and guide new singers in the choir.

Tim McLellan has served as bass section leader at St. Bart's since 2005. Throughout his musical career, he has sung and conducted at Catholic, Lutheran, Methodist, Baptist, and Assembly of God churches. He holds degrees in music from Cal Poly State University and the University of Washington.
