Wendy Hering, LMT

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.

Holly completed her massage therapy license at Cortiva School of Massage Therapy in Chicago, IL. After graduating massage school, she worked with a number of chiropractors and with a wide variety of clients, helping patients recover from major surgeries to minor muscle aches, as well as providing maintenance therapy. To that end, she has expanded her expertise to include cupping and Graston techniques. Holly has developed a passion for working with athletes and bodybuilders, helping them with maintenance and recovery. She started her fitness journey in a CrossFit gym, and recently transitioned to bodybuilding and competing in NPC competitions in the wellness category. She enjoys training others in strength and conditioning, as well as in functional movements to achieve their goals. Being a bodybuilder herself, she knows how important body work and mobility is for feeling and performing the best and wants to help others perform at their highest potential.

Five star review

I found Courtney and the cupping offered was just what I needed! It felt like an almost instantaneous fix. He helped me learn stretches and exercises to strengthen my shoulders for long-term results. My tendinitis has gotten a lot better but I still go in for cupping before meets or during heavy training. It keeps my muscles loose and keeps them from straining or tearing. All in all, Courtney has helped me out a lot in my athletic career.

Five star review

I was refereed to PR Lab by a friend. I came here on two different occasions to seek treatment 1) grade 2 lateral sprained ankle and 2) lower back strain muscle. Dr. Courtney Warren and Wendy were very thought with the treatment for both of these injuries. I was able to make a fast recovery and go back to my regular activities due to dry needling and cupping therapy. I highly recommend this place to anyone who seeks physical therapy or overall treatment for range of motion.
