Client Stories

See how my clients have overcome injuries, built strength, and achieved their running and hiking goals with my personalized approach.

“Before I began working with Chelsea, I believed my knee and back problems were just my new way of life; I'd accepted that I couldn't run anymore. But when these issues threatened to end my hiking hobby and began to impair my general mobility, I found Chelsea. I was so impressed by her thoroughness and saw huge improvements after just one week. Now I can do things that would've been impossible before working with her. I have a plan to get back into running, and I've just returned from hiking in Patagonia. I couldn't believe how great I felt after long days of hiking in the mountains, and it's all because of Chelsea!”

“If you have been told to stop an activity you love due to an injury please see Chelsea. Chelsea has given back my joy of running and I cannot thank her enough. She is incredibly professional, kind and caring. The exercises she has given me have worked quickly and have restored me to better than baseline. She knows her stuff! She is incredibly easy to talk to and I always feel heard. If you are looking for help, look no further. Call Chelsea!.”

Heidi S

“As a lifelong competitive athlete and active outdoors woman, I am no stranger to injury and knew my body to be quite resilient. Then, I suffered a injury which left me feeling scared and hopeless about whether or not I would be able to enjoy an active life without fear again.

Through our work together, Chelsea not only helped me heal and regain strength, but she supported me in rebuilding trust with my body. She is both impressive in her capabilities and knowledge as a PT and coach, and deeply invested in her clients' wellbeing and joy. If you’re concerned that chronic pain and fear are going to keep you down and out of an active life worth living, call this woman. She will change your life like she changed mine!”
