Meet Our Olympia Ninja City Staff

Bonnie Campbell - Gym Manager

I began my career with Olympiad in 1984 here at our West location. In 1990, I transferred to Olympiad Ellisville to open the new location as the Progressive Director. In 2004, I transferred back to Olympiad West to become the Gym Manager. I have been a coach for more than 20 years and was a competitive gymnast. I love working for Olympiad because I truly believe it is good for kids. I can answer questions about general gym policies and programs and anything else you’d like to know! I can be reached at

Katherine Potorff - Ninja City Ninja Instructor

As a young child I always wanted to do gymnastics, but it wasn't until I was 13 that I finally convinced my parents and they agreed on one condition; that if I wanted to take more classes I had to pay for them myself. So from this first class, I started saving and working all kinds of odd jobs. The skills I have learned from taking gymnastics were appealing; discipline, determination, coordination and how it affected me mentally and physically. I started working as an instructor at Team Central at the age of 15. I have been teaching ninja since 2015 and I am now the Ninja director at our Mid Rivers location and have been a part of the program since its inception. I am always availale to answer questions and care for the needs of our ninja kids beginner - advanced. I can be reached at

Jennifer Phillips - Ninja City Ninja Instructor

I was a student at Olympiad North for eight years as a child. I loved the sport and was passionate about it. I went on the be a cheerleader at St. Charles High School. In 2004, I graduated from Maryville University with a Bachelor's degree in Chemistry and Biology. I worked as a specialist in the Air Pollution Control program for the St. Louis County Health Department for 5 years. At that time, I had my second child and decided to be a stay-at-home mom. My kids (now three of them) attended Olympia Manchester since they were very young. After my third was born, my husband and I started rock climbing and training for obstacle course competitions. I have now competed in several of them and advanced to the national level in the National Ninja League. I decided to go back to work part-time in 2016 at Olympia Manchester. I now teach tumble bees, girls gymnastics, cheer, and ninja; sharing my passion with children and loving every minute of it!  I can be reached at
