Associate Organist

Janie Prim is a well-known, San Diego-based pianist/accompanist and is recognized for her church organ skills. Forced into subbing for her mother at age 14, she played two services well enough that she was immediately offered a job at the nearby Methodist Church.

Ms. Prim continued as a self-taught organist, working in several churches in the San Diego area until she was hired as interim organist at St. James-by-the-Sea Episcopal Church in La Jolla. While in this position, she had lessons from Robert Plimpton and Jared Jacobsen on the 64-rank pipe organ at St. James.

In 1995, Janie accepted the organist position at St. Bartholomew’s Church. She continues organ studies with Martin Green, canon at St Paul's Cathedral, and maintains an active musical life as music director/chorus mistress for Lyric Opera San Diego and principal outreach accompanist and principal dance rehearsal pianist for San Diego Opera, as well as working for Cygnet Theatre and the Old Globe Theatre for auditions.  Ms. Prim also has a private studio for coaching and accompanying singers. 

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. When he's not at St. Bart's, he teaches math and music to middle school students in San Diego Unified School District.

Sean McCormac, tenor section since 2011. Home-schooled from kindergarten through 12th grade, he attained his bachelor’s degree in vocal performance from Cal State Northridge. Sean also serves as tenor section leader for the La Jolla Symphony Chorus. He is a frequent performer with the San Diego Pro Arte Voices and has provided solo work for the Palomar College Chorale and Bodhi Tree Concerts. 


Beatriz Avila Casillas, alto section leader. Beatriz’s life revolves around two things: singing and playing viola. Her musical career began at Palomar College when she entered the Applied Music Program. Here, she studied and performed voice. She graduated with an Associate’s of Arts Degree in Music Spring of 2018 and has plans to further her education. During the time Beatriz was in school, she volunteered as a violin/viola teacher at Renaissance Institute of Music (RIOM). She continues to teach groups of students as well as private lessons; however, she is now the Program Manager of RIOM. Aside from this, she participates in the Center Chorale of Escondido as a Voice Scholar and in MiraCosta College Orchestra as a violist.
