Rylee Scroggs graduated from Springs Studios for Academic Excellence this past May. I have been dancing for fifteen years, twelve of which were competitive. This past summer I graduated from Dance Unlimited in Colorado Springs, with training in ballet, pointe, tap, jazz, hip hop, musical theater, contemporary, and lyrical. During my high school career, I got the opportunity to train at Arts Immersion for two years, focusing on ballet, modern, and technical training throughout the day, and the other two at Springs Studios high-performance program where I got to focus on my dance training and incorporate it into my schoolwork. For the past four years, I have had the opportunity to be a teacher’s assistant, teach dance at birthday parties, and in classes of all different levels and genres. I have also been able to choreograph different groups and solos for choreography showcases and recital at Dance Unlimited, as well as teaching summer camps at Synergy Dance Academy. This next fall I will be majoring in dance at Pikes Peak Community College and earning an Associate of Arts degree before transferring to New York in two years to study dance theater. I have always had a passion for performing, but over the years I have really developed a passion for teaching and choreographing, and hope to help find other dancers find their passions as well.
