Singer ~ Actress ~ Gigging Musician
I am a 21 year old professional singer, actress and gigging musician, with home bases in the Chicago, Illinois and La Crosse, Wisconsin areas. I'm currently a 3rd year BFA Musical Theatre student, studying at Viterbo University, Conservatory for the Performing Arts. I'll be graduating in spring of '26 and am planning a dual career in the arts, balancing time on stage in musicals and plays with time working with my guitar as a gigging musician.
As an actress, I love trying new things and take pride in bringing my best to every audition and performance. I have been trained in stage combat and specialty makeup, and have understudy and swing experience. Conservatory Dance and Music Minors enhance my skill set and ensure that I bring the right level of energy and musicality to any role. Some favorite roles include Jane in Disney's Tarzan: The Stage Musical (2024), Hamlet in Rosencrantz and Guildenstern are Dead (2024) and most recently, Pearl in These Shining Lives (2025).
As a musician, I am known for for producing my own series of Facebook and Instagram Live Quarantine Concerts, leading to a feature story on Chicago's WGN news. I won the DuPage County Fair talent competition two years running, and have sung the National Anthem for Chicago White Sox games in 2021 and 2022! I play the guitar and ukulele and run my own successful solo entertainment business. I've been gigging at bars, restaurants, private parties and special events throughout the Western Suburbs and Chicagoland area since 2020, and cover a wide variety of music, including pop, rock, country, standards and more.
I am currently seeking Musical Theatre and Gigging opportunities throughout the Western Suburbs of Chicago, and am booking dates for summer of 2025. Check out the information and samples of my work below, feel free to download my Theatrical Headshot and Resume, and use the contact form to get in touch with me. I'm looking forward to answering your questions and making a new connection.
