Kelsy Rayl is a Doctor of Physical Therapy (DPT) who specializes in vestibular rehabilitation, concussions, and general orthopedics. She works at Activcore in Castle Rock, CO which is located inside Optimal Health Chiropractic.

Kelsy graduated Summa Cum Laude from Kansas State University with a Bachelors of Science in Kinesiology. She then attended the University of Kansas Medical Center where she earned her Doctorate of Physical Therapy. Kelsy has continued to expand her expertise in the vestibular and concussion realms as well as in orthopedics. Kelsy is a certified vestibular therapist through the American Institute of Balance and concussion certified by both the American Institute of Balance and ImPACT. Additionally, she has completed her Certified Orthopedic Manipulative Therapist (COMT) as well as her Trigger Point Dry Needling (TPDN) certification.

Having taken yearly family vacations to Colorado growing up, Kelsy is excited to be a Colorado resident and enjoy the outdoor activities year round. In her free time, she opts for taking in the beautiful Colorado scenery while hiking, mountain biking, cycling, skiing, snowboarding, and paddle boarding. When she’s not outside, Kelsy enjoys reading, tending to her growing plant collection, snuggling with her two cats, and spending time with family.

My Client Reviews

Dr. Kelsy Rayl has been my physical therapist for about half of 2021. I was referred to her after a different therapist could not get a handle on my low back/hip issue that was incredibly painful and even limited walking. Kelsy honed in on it correctly from the beginning and got me functionally back on my feet with compassion, diligence, humor and, above all, knowledge and skill. I cannot say enough good things about her! Now that Kelsy is in Castle Rock, I will drive from Denver if I need her skills again.

Dr. Kelsey Rayl is a fabulous physical therapist. She has great ideas, and she is creative in finding ways for a patient to do her exercises. She is positive, encouraging, upbeat, and always smiling. I highly recommend her!!!

Activcore PT worked great on the pain I was encountering with my shoulder blades. I have had previous PT sessions focusing on this injury, but the Redcord system utilized by Activcore has given me the best results and relief from pain by far. I will be going back again soon for a follow up and would recommend Activcore to anyone seeking professional and effective physical therapy. Thanks Dr. Kelsy Rayl !!!

I’d never had much in the way of back problems until about a year ago. Having just turned 60 at the time, I figured it was just age catching up with me. Mine was mostly lower back stuff - whose isn’t? Anyway, I finally decided to inquire whether there was anything that could be done and in furtherance of this decision I saw Dr. Kelsy Rayl at Activcore in Castle Rock, Colorado. When I first walked in to the treatment room I was puzzled by the ropes hanging from some contraption on the ceiling. I shortly learned that this was the “Redcord” system she uses. It basically takes weight off the major muscles by suspending the majority of one’s body weight, thus taking that weight out of play and isolating those minor muscles which, when they become inflamed and stop working, force the major muscles to take over the load. Hence the issues with my back. Anyway, with a good bit of manual manipulation, some dry needling (really not painful - mostly feels like a minor cramp in the targeted muscle), and the aforementioned Redcord work, I gained a significant amount of movement in my back and legs, and the pain level dropped significantly. The next morning it was easy to put my shoes on for the first time in a while. So, the long and short of it is that I’d highly recommend seeing Dr. Kelsy Rayl for what ails ya.

Definitely recommended. I slept wrong and had a super stiff neck. It was bad enough I would move my shoulders to look around. With one dry needling session and Redcord therapy, and a few days rest, I was back to baseline. The Redcord modality made me feel like little to nothing was happening, but it was amazing to feel small/deep neck muscles being activated/isolated. i.e. It doesn't take much to fix a big problem! Dr. Kelsy Rayl is the best.

Best physical therapy I have ever had! Dr. Kelsy Rayl really focused on my issues with new methods that really focused on my pain. Best thing is one patient at a time and in private. She works miracles as a migraine sufferer. Awesome!


I can't say enough good things about my experience. Kelsy is a true professional. Not only did she take the time to thoroughly explain my treatment, she also gave me stretches and continuing exercises I could do to assist with my recovery. She's knowledgeable and obviously cares about her patients. Highly recommend it.

I am so thankful for the vestibular help provided by Kelsy! She is extremely patient and is a great listener. I felt comfortable and educated as she assisted me in my recovery. I highly recommend Dr. Kelsy Rayl.

After months of non-answers from neurologists, ENTs, general practitioners, etc. Kelsy was the first to provide me with some answers regarding my symptoms of dizziness, imbalance, vertigo, and nausea. Vertigo and nausea quickly resolved after just 2 sessions, and I've since made steady progress on other fronts. Treatment was/is well tailored, and she was extremely knowledgeable and adaptable as things progressed. Even a bout of tinnitus that cropped up during treatment was quickly resolved with some jaw exercises. I absolutely recommend her if you are struggling with any of these symptoms.

Kelsy helped me recover from my concussion and was very supportive and willing to answer any and all questions I had. Highly recommend checking her out for any physical therapy that you might need.

Kelsy is an amazing PT! She is a great listener and gears your therapy not only toward what you need to recover but also toward the activities to which you’d like to return. Everyone at the practice is so nice.

Kelsy has been my therapist & she has helped me recover from a hip injury. I really appreciate how she explained what was happening. The exercises she has given me helped me progress!  I highly recommend her!

I scheduled a consultation hoping they would be able to help me with my medical issues. The treatment that I needed was not something that they offered. They were very upfront about that, instead of leading me on or scheduling out services that would not help my situation. I mentioned that I was new to the area and Kelsy offered to help me find a center that might provide the services that I need. She called me the next day with the names of 2 offices that could help. I appreciate the awesome customer service.

I absolutely LOVE my P.T. Dr. Kelsy Rayl. She is incredible, knowledgeable and determined to help each body improve to optimal level. I was in a terrible car collision, and I received the cognitive and physical rehabilitation to restore my performance in a short span of time with their philosophies and methods. Thank you!

I was diagnosed with a Chiari Malformation a year ago and I suffered from severe headaches, dizzy spells, fatigue, and much more, for most of my life. I went through two rounds of therapy (with Kelsy) and I’ve been headache/dizzy spell free for five months and I have much more energy than ever before!
