Our Teachers

Angie Davids

Voice, Clarinet, Saxophone

Angie Davids is from a very musical family. With both parents having music degrees, music was a way of life. All of Angie’s siblings including herself sing, play piano and at least one other instrument well. Angie’s choice for the “other instrument” was clarinet. She enjoyed playing first chair throughout high school and directing the Indiana State champion (class B) marching band as a drum major. Vocal training was obtained through her mother whose degree was in voice as well as Purdue’s Musical Organization. Now she keeps her vocal chords active with leading worship at Faith Church’s Cedar Lake Campus and church choir. She loves hearing students grow in their musical ability and seeing them enjoy all the benefits music brings to their lives.
