Our Leadership Team

Our vision is for Teton Music School to be the heart of music education and performance experiences for our diverse community. We value inclusion, creativity, passion, and transparency.

With more than two decades of arts administration, marketing and fundraising experience, Amanda has worked for the Chicago Symphony Orchestra, Minnesota Orchestra, Indiana University School of Music, Mahler Chamber Orchestra, Grand Teton Music Festival and, most recently, Dancers’ Workshop. She is driven by possibility and committed to building bridges through music within our community, as well as between our community and the larger arts world.

She plays French horn in the Jackson Hole Brass Quintet and dabbles (in the privacy of her own home) on a haunted family accordion. She has served on the boards of The Center for The Arts, Center Residents Council, Jackson Hole Chamber of Commerce, Riot Act, Inc., and Old Bill’s Fun Run and as a grants panelist for National Endowment for the Arts.
