“I have battled chronic back issues for years and have sought extensive treatment with up and down success. I have treated with Kyle for about 5 months, and I am so thankful that I found him. Kyle brings a unique skill set of physical therapy and sports training, which has finally gotten me on the right track. Perhaps even more significant, is his personality and caring approach to his craft. Kyle is an excellent listener who truly cares about his patients. He's a wonderful person, who I am very thankful to know. I highly recommend him!” - Mike

“I was recently recovering from shoulder surgery when I met Kyle. Don’t be fooled by his youth - he’s very knowledgeable and professional and helped me tremendously. He willingly and graciously treated me in conjunction with the physical therapist I was seeing near my home. He had excellent ideas on exercises I could do on my own and I always felt better after one of our treatment sessions. I would highly recommend Kyle for your physical therapy needs.” - Stephanie

“I struggled with pain for three years after mid back fractures at age 62 and had tried various treatments before going to Onyx. I knew immediately when I met Kyle that his approach would be different. He took the time carefully assess my situation and then to explain what was going on. Through manipulation, dry needling and a home exercise program, I am now back to running and doing the things I love pain-free. It has been truly remarkable. I am grateful to have a PT like Kyle who was willing to challenge me to push regain my life again!” - Maureen

“Kyle was amazing! I repeatedly pull my hamstring and quads and he worked with me for weeks to build up the strength in the parts of the muscles that get strained more often. My legs feel good as new! He is very smart and cares about seeing his clients get better! 10/10 would recommend him for any physical therapy needs!” - Maeve

“You won’t find better than Onyx for sports specific Physical Therapy. They deeply understand the unique way the body moves and works when engaged in high level athletics - or just in everyday life. They quickly brought my son back from a baseball injury. He’s not only back to playing- but at a much higher level because he has learned how to use his body from Kyle at Onyx. Highly recommend!” - Amanda

“We had a wonderful experience with our physical therapist, Kyle when our son injured his shoulder in a baseball game. Kyle was thorough in his assessment, helped our son feel at ease, and the communication was great throughout the whole process. Kyle’s recommendations and treatment plan was spot on and our son was able to return gradually and safely to the sport he loves. As parents, we appreciated vast knowledge and experience in sports medicine and his positive and friendly attitude. We would highly recommend Kyle to friends and family.” - Alyssa

“I have been very impressed with ONYX’s return to play program. After my initial Post-Op PT services I was able to gain some function but my insurance ran out and I was not where I needed to be yet. I decided to take a chance with you and see if your treatment plan would allow me to return to tennis 100%. You were very deliberate in your methodology and timeframe for my return without misleading me. As a healthcare professional myself I appreciated your approach. The good results I am seeing is a direct result of your guidance and inspiration you give me. Thank you very much! Could not have done it without you and will always be grateful.” - Matthew

“My son is a competitive football player and recently hurt his back.

I know that if a sports injury occurs again to my son, I will be sending him to ONYX Sports Physical Therapy for their expertise, excellent communication, and high level of care!” - Joan
