Elizabeth Garrett, BA (FAS)

General Manager


Elizabeth Garrett fell in love with choral music at an early age, singing in her grade school choir.  High school brought her to Cawthra Park School for the Arts in Mississauga, Ontario, where she continued singing in vocal ensembles while taking courses in Theatre, Dance, Musical Theatre, and Photography.


Elizabeth received an academic scholarship to attend the Fine Arts Studies degree program at York University, where her major focused on the interplay between arts disciplines and culture, politics and history.   During her studies she was accepted into the Classical Voice Performance courses and sang with the York U. Chamber choir.  She also started and was first president of the York U. Fine Arts Studies Student Association.


Since moving to Calgary, she has sung with a number of groups including Spiritus and Fresh Blend Acapella.


Previous arts work experience includes Marketing Coordinator positions at Calgary Opera and the CPO.   After taking time away to raise children, Elizabeth is thrilled to be back in arts administration and working with Calgary Boys’ Choir.

Kari Orosz, BA (Arch), BA (Hist)

Principal Accompanist

Kari Orosz was born and raised on a farm in rural Saskatchewan. She hails from a musical family and grew up singing and playing any instrument within reach. She began studying piano at age five and started working as a church accompanist at age eleven, a profession in which she has continued ever since. Kari is the organist for St Thomas United Church in Calgary and has been a part of their music team since 2005; there she accompanies two choirs, plays in the orchestra and guitar group, and enjoys providing a wide variety of music for their congregation during their Sunday services.


While the piano is her primary instrument, Kari is a true multi-instrumentalist. She plays pipe organ & electric organ as well as an antique pump organ that she inherited from her family in Muskoka. She studied trumpet for years and was a member of the Saskatchewan Provincial Honour Band. She loves playing a wide variety of instruments and has taught herself how to play guitar, autoharp, double bass, pennywhistle and bodhran. Kari is also a singer and she has sung alto & soprano in many choirs over the years, including the Saskatoon Symphony Chorus and the Calgary Philharmonic Chorus. She received her Grade 10 Piano from the Royal Conservatory of Music in 2003 and holds two Bachelor of Arts degrees in Archaeology & History from the University of Calgary.


During the COVID-19 pandemic when musicians faced the unique challenge of making and sharing music safely, Kari expanded her skills into the virtual space. She borrowed microphones & mixers and learned how to make recordings and do sound editing, and this opened up an entirely new realm of musical possibilities. She has since made hundreds of solo recordings and has compiled many virtual pieces for her fellow singers and instrumentalists.
