About Katie Kostner


I am a professional singer, actress, musician and songwriter with a passion for music and the stage!


I'm also a soon to be second year BFA Musical Theatre student at Viterbo University, Conservatory for the Performing Arts, in La Crosse, Wisconsin, with minors in music and dance and a deep desire to learn and grow as a performer. 


I love every moment I spend on stage, and consider every musical role or gig I play training for my career.


Locally, I am known for performing live at area events, as well as for producing my own series of Facebook and Instagram Live Quarantine Concerts, leading to a feature story on Chicago's WGN news.  I've done some really cool things, including winning the DuPage County Fair talent competion two years running, and singing the National Anthem before a Chicago White Sox game in 2021 and 2022!


I have appeared in multiple plays and musicals over the past several years, most recently as Dragon in Shrek the Musical, as well as an Assistant Director and Swing in the Viterbo Student Theatre Project production of Heathers, the Musical. 


In addition to my love for musical theatre, I play the guitar and ukulele, write music and sing with a vocal range that suits a wide variety of styles, from Broadway to current pop, rock, folk, country and beyond! From quiet, ambient music to rocking the center stage, I can put together a show you'll love!


I am available to perform for your special event!  You can count on me to arrive and set up on time, with my own sound system at the ready.  Rates are negotiable and reasonable, and will help support me as I work my way through college.  Check out the information below, and use the contact form to get in touch with me.  I can't wait to hear from you!
