 Katie Gerber


Double degree in Vocal Performance and Music Education at I.U Jacobs School of Music
MM in Voice at San Francisco Conservatory of Music

Katherine Gerber completed her undergraduate degree at the I.U Jacobs School of Music, where she received a double degree in Vocal Performance and Music Education with a Choral Music emphasis. Following this, Katherine resided in Sydney, Australia for several years, where she sang such roles as Antonia in “Tales of Hoffmann,” with the Sydney Madrigal Singers, and sang solos in several different oratorio works throughout the greater Sydney area. While in Sydney, Katherine also spent many years as Head of the Vocal Department at Stella Maris College, where she directed several of the school’s internationally award-winning choruses. 

Katherine is now based in San Francisco, and has completed her MM in Voice at San Francisco Conservatory of Music. At SFCM, Katherine sang the role of Pamina in “The Magic Flute”, Clori in “L’Egisto”, and the role of Armida in “Rinaldo”, with Conservatory Baroque. Upon graduating from SFCM, Katherine was awarded with several distinctions, including the Dean's Award in Excellence for Opera Performance, and the Dean's Award for Performance in Baroque Vocal Music. Katherine is now studying with mezzo-soprano and Voice Chair of SFCM, Catherine Cook. 

Following Katherine's graduation, she has worked as a choral director in several schools and choruses, including the world-renowned children's chorus, the Piedmont East Bay Children's Chorus. Katherine has also directed music at two prominent Bay Area churches over the past several years, while maintaining a busy private voice studio at home. She has now spent the past four years as Music Teacher and Choral Director for grades Pre-K-5th at the Nueva School in Hillsborough, where she also taught voice, and directed the Glee Club. Katherine is also Music Director and Pianist at Grace Lutheran Church in San Francisco.

With many years of experience as a music educator and choral director, Katherine has spent much of this time refining her own unique approach in choral education. With her pedagogical approach largely founded upon the Kodaly method, Katherine's commitment to dance and movement, drama, speech, and improvisation makes even the simplest piece of music come alive in the classroom, allowing children to experience and immerse themselves in the joy of music-making. Katherine believes rehearsing should be a joyous experience for children, much like playing, but with plenty of captivating challenges in order to give every child a sense of pride and dedication to their craft. Katherine is dedicated to making her rehearsal environment a warm and safe place for her singers, where they come every week bursting with excitement to be together, to sing, to dance, to learn, and to create life-long friendships with a common goal of choral excellence.
