Sarah Atenhan

Owner/Master Instructor

A native of Chicago, Illinois, Sarah Atenhan began her training in classical ballet and modern at the Academy of Movement & Music under the direction of Stephanie Clemens. Once in high school, she continued her pre-professional training at Lou Conte Dance Studio (home of Hubbard Street Dance Chicago), and with her high school’s performing company, Orchesis Dance Troupe under the direction of Lucy Riner. While working with Orchesis, Sarah discovered her love of choreography. Her first work, Until I Burst, was featured in 2003’s Dance Chicago Festival at the Athenaeum Theatre.

Sarah is a graduate of the University of Illinois at Urbana-Champaign. She received a Bachelor of Science degree in Psychology with concentrations in Dance and Neuroscience. Sarah studied and performed with the UIUC’s Department of Dance, and 3Spot Dance Troupe where she choreographed numerous works for her fellow artists.

Upon graduation, Sarah immersed herself in the Chicago dance scene, performing with many companies and choreographers including: ology Dance, Chicago Dance Crash, Jessica Deahr, Chicago Freelance Dance, Ronn Stewart, and B.I.S.I. Dance. While working with B.I.S.I. Dance, Sarah trained and performed aerial acrobatics. In addition to her performing career, she has been an instructor, choreographer, and associate director with Mohler Dance Academy and M3 Dance since 2009.

In 2012, Sarah sustained a major cervical spine injury during training, requiring surgery. During her recovery, she acquired a second career as a freelance project manager for communication agencies. Sarah has since enjoyed 4+ years of producing videos, managing large teams, and creating live events for Fortune 500 companies.

In 2016, Sarah re-entered the world of aerial acrobatics. She has received both her Aerial Yoga and Aerial Fitness Teacher Certifications through AIR® Aerial Fitness, and has been instructing many classes a week ever since.

Sarah is thrilled to join the Serenite’ Fitness community. She is looking forward to working with clients and staff – supporting all members in achieving a more balanced and healthy lifestyle.
