Cherie Sussner


Cherie Sussner grew up in Menno, SD and tried out every sport available to her in a small town. From that experience came a desire to understand the body’s ability to become more effective during sport and activity, so she went on to gain her bachelor’s in Exercise Science at the University of Sioux Falls. While completing her bachelor’s, she also competed in volleyball and track. Cherie then pursued her Master’s degree from the University of Memphis. During those two years, she gained more experience as a teaching and research assistant at the University of Memphis and was also an assistant volleyball coach at Rhodes College. From there, she was an assistant volleyball coach at Minnesota State Moorhead and has since pursued personal training as her primary endeavor.

She’s trained in Sioux Falls as well as New York City. While in New York, she became NSCA-CPT certified and since being back in Sioux Falls, she has completed her RKC (Russian Kettlebell Certification), TRX, as well as a nutrition certification by AASDN. Cherie married her husband Jason in May of 2013 and they recently had their first child, a little boy named Ian. She has competed in many marathons including Boston, and has also done an Ironman competition. Her passion for endurance training and her desire to get stronger have helped many clients smash their goals.

Tim Feathers

ACSM-Certified Personal Trainer

Accomplishments: Began competing in strongman during the summer of 2012 and ever since then it’s been a passion of mine. I’ve competed in over 20 competitions including 4 Nationals across the country. I am currently the state representative of South Dakota for United States Strongman, Inc. I’ve worked at commercial gyms in the past but training at Results PT has provided me an incredible place to work. From the best equipment, support from coworkers and amazing clients this gym is by far the best facility I’ve had the opportunity to work at.

After starting off my college career studying Engineering I came to the conclusion that I had no interest in that field. I finally decided to study Exercise Science at Lake Superior State University where I attained my Bachelors Degree in 2011. The human body is capable of so many amazing things and I wanted to help others achieve goals they wanted to accomplish but didn’t think they could do on their own. I’ve had clients from various backgrounds including lawyers, doctors, mechanics to entrepreneurs all with different goals. Improving mobility/flexibility, fat loss and increasing strength are typical goals and utilizing my background and the Functional Movement Screening we are able to accomplish these.
