joy heitz gym managerJoy Heitz - Gym Manager

Born and raised in South St. Louis, my roots run deep within the city. I love this place we call home and all its history, tradition, and great food it has to offer. As a former gymnast, coach, and now gym mom; gymnastics has greatly influenced who I am and it still a prominent part of my life. I began my journey with Olympia Gymnastics as a full time coach in January 2011. I was given the opportunity to manage Olympia Rock Hill in fall 2019. I have a wonderful husband and two beautiful children. I enjoy all things related to music and the outdoors. I have a passion for life, people, and gymnastics; and I'm grateful for the opportunity to share that with the local community! Joy can answer questions about anything gym related.
