Originally from New York and raised in the midwest, Kat started her career as a classical singer and pianist with a passion for contemporary music, performing with Absolute Ensemble under conductor Kristjan Jårvi and the Manhattan Contemporary Ensemble, premiering works by Tobias Picker (Symphony for Soprano and Orchestra), Ernst Widmer, Aaron Jay Kernis, and William Kraft.

Her passion for children and teens of all abilities inspired Kat to create and facilitate songwriting and recording workshops for children, teens, and young adults throughout Greater Los Angeles, at The Miracle Project, the HELP group, and Vista Del Mar Child and Family Services, to foster positive self-esteem and self-advocacy through creativity. In addition, Kat has served as music director of the Moses-Aaron Project, a program to support children and teens with autism and other special needs to engage in personal spiritual practice, read Torah, and become Bar and Bat Mitzvot.
