Staff & Board

Pam Mowry
Executive Director

Pam Mowry is proud to be Canterbury Voices’ Executive Director, leading the staff team since 2016. She has nearly twenty-five years of nonprofit management experience, primarily in the areas of fundraising, board development and event management. Mowry’s career began in 1998 at the Oklahoma Arts Institute at Quartz Mountain. In 2005, she joined the staff of Lyric Theatre of Oklahoma just as their capital campaign was getting underway to renovate and endow three properties on NW 16th Street in Oklahoma City, known as the Plaza District. Lyric was successful in reaching its goal to double their artistic programming and expand their community outreach when the historic Plaza Theatre opened in December 2007. Mowry left Lyric in 2012 to become the Executive Director of Oklahoma AIDS Care Fund, and coordinated three Red Tie Night events before joining the Boys & Girls Clubs of Oklahoma County staff.

Mowry serves on the Oklahoma Arts Institute’s Artistic Advisory Panel in Choral Music. She has served on the Oklahoma State University College of Arts & Sciences Alumni Board and chaired the 2012 Oklahoma Arts Conference in Oklahoma City. She has been a guest speaker and panelist on various fundraising topics, including capital campaigns, corporate sponsorships, and creative fundraising ideas.

Pam earned a Bachelor of Music with Elected Studies in Business degree from Oklahoma State University. During her time at OSU, she had the honor and privilege of studying choral music with Dr. Jerry McCoy. Mowry has also sung with Canterbury Voices, Stillwater Chamber Singers, and Windsong ensembles.
