Katherine "Kat" Feller was born in San Francisco, California, to Roland and Lois Feller. She grew up in a musical household, and began violin lessons at 8 years old, later adding viola.
While studying in San Francisco, she took classes at San Francisco's renowned American
Conservatory Theater as well as participating in her middle and high school drama clubs
and musical productions. It was during this time she began to realize how much
she loved singing and acting, and began taking private voice lessons in addition to violin
and viola.
When she went to CSU Chico for college, she jumped at the chance to work with her
professors and fellow students in the theater, musical theater, and music departments in anything and everything she could. She was especially active in CSUC's opera workshop under Ying Yeh, intensely honing her craft and performing such roles as Valencienne (The Merry Widow) and Adele (Die Fledermaus). During this time, she also performed off campus in various community theater productions. At the end of her time at CSUC, she was delighted to accept the honor of being a soloist at her commencement ceremony. She performed the Alma Mater for a stadium filled with her fellow graduates and their friends and family.
In the summer of 2010, she had an opportunity to work with Lamplighters Music
Theater in San Francisco for their summer production of Pirates of Penzance, and had a
wonderful experience. After returning to San Francisco after graduation in 2011, she resumed working with the Lamplighters, most recently appearing as a fairy in Iolanthe. In addition to Lamplighters, she has also sung with several other local opera companies. A recent such project was Offenbach's The Grand Duchess of Gerolstein with Pocket Opera.
Still in San Francisco, she continues working in music and theater, performing as well as teaching young talent of the future.
