Erin founded Erin Shepherd Voice Studio in 2005. Erin is a teacher of voice who constantly strives to learn more about vocal sound, current voice science, and relational instruction. Her specialties include teaching vocal technique, the diagnosis and repair of vocal dysfunction, and the building of the singing voice. This dynamic and committed educator actively serves her musical community by coaching and adjudicating for music associations such as National Association of Teachers of Singing, the High School Honors Performance Series at Carnegie Hall, Schmidt Youth Vocal Competition,  and the Georgia Governor’s Honor’s Program. She taught courses on Musical Theatre and Acoustics at the Summer Institute for the Gifted (SIG) at Emory University from 2016-2017.

In 2018, Erin was elected to the board of GANATS (Georgia branch of the National Association of Teachers of Singing), and began serving in 2019 as the GANATS Chair of Private Studio Outreach and Support.  

Also in 2018, she co-founded the Performing Arts Conservatory of Atlanta (PACA), which provides scholarships for high school students who can't afford private voice lessons. In their first year, they gave over $3000 in scholarships to students in need.

Erin is the founder and moderator of the Atlanta Voice Community Forum and the co-founder of The Voice Alliance, both of which serve to form community and provide a learning platform for local singers and teachers of singing. 

Erin is grateful for the influence and care of her teachers at Juilliard School of Music, the Metropolitan Opera, Lincoln Center, Emory University, and The Atlanta Opera.  Erin  teaches at Holy Innocents Episcopal School and from her home studio in Cabbagetown — all in Atlanta.
