Pamela Heiser

Executive Director of Musical Operations

Pam has a long history with the choirs starting in 2002 as an accompanist with the boys’ touring choirs. It was on her first trip to Oregon that she learned to appreciate this organization’s safety protocols and what it means to repeat roll call until you get it right. Her other favorite memories are traveling to Australia and New Zealand with her son, Andrew, where they performed on the Sydney Opera House stage together and managing the girl choir’s most recent performance tour to Estonia and Finland. Pam earned a Master’s Degree in Music Education from the University of Illinois at Urbana-Champaign, studying under the late Eunice Boardman. She also holds a Bachelor’s of Music Education from the University of Wisconsin-Eau Claire. When Pam is not decluttering her home or office, you might find her directing a musical, accompanying a school choir, reading a book, or enjoying time with her family in the kitchen or at church.

Michael Hagerty

"Hi, I am Mike Hagerty and I joined the choir’s Board of Directors to give back to an organization that I love and that my son Jacob is a member of. As a boy, I was one of the charter members of the choir, and by being a part of the choir, it fostered my love of music and helped me become the person I am today. Volunteering on the board allows me to help make sure the Choir is able to provide an opportunity for young singers to express and grow their own love for music and gain experiences that will last a lifetime. I also volunteer as a Scout leader with a local Boy Scout troop and I'm involved as a board of director for a local youth rec soccer league."
