Chandler Flores


Chandler grew up in northern Arizona. She went to NAU for her bachelors degree in Biology, and Carrington College for her degree as a PTA. She’s been practicing in the healthcare field for many years in many mediums, and has nothing but great things to say about the field as a whole, providing ever changing environments and growth opportunities. She’s enjoyed all things outdoors from biking, hiking and skiing since she was a kid. One of her favorite things about practicing as a clinician has been being able create goals together with her patients directly relating to things and activities that they love to do to provide motivation and drive to reach those goals.

Wendy Hering


Growing up, I threw snowballs, baseballs, javelins, and practiced shooting a hockey puck millions of times.

I wanted to win an Olympic gold medal and play in the NHL. After several knee and shoulder surgeries, it finally dawned on my that I needed to start paying attention. This led me to a career in massage therapy after realizing the profound effect massage had on my ice hockey damaged knee.

I wish I had done things differently; I now try to help everyone pay more attention to what they are doing to their one and only body.

I hope my experiences with some of the most intelligent people in the world of strength and conditioning will forever change how we look at movement, strength, and mobility.
