Katie started her dance career at the age of four in Colorado Springs, Colorado. She trained at Dance Unlimited for fourteen years, studying styles such as ballet, jazz, tap, lyrical, hip hop, and musical theatre. She competed for ten of those years and attended conventions with instructors and choreographers from around the dance world.


Katie is currently a dance major at Pikes Peak Community College where she is working on many projects involving creative dance as well as film and photography. She has been a member of the student company, High Altitude Dance Ensemble, at PPCC for two years. While attending college she has choreographed her own group piece that was presented in a showcase with the theme of technology and produced a dance for camera piece, called “Tranquil”, that was shown during the spring 2016 dance showcase. Her time at PPCC has been very dance oriented and she continues to grow as she dives deeper into the world of dance.


Her teaching career began at Cutting Edge Dance and Acro, teaching styles from ballet to hip hop. She has worked with all ages, including adults, teaching many different techniques. Katie's goal for teaching is to show that anyone can dance; it’s just a matter of working together to maintain a common goal.
