Extremely effective services that helped my back pain and posture improve immensely. Every appointment was met with kindness and understanding. No matter how busy or how slow the staff was, every appointment had the same positive impact I needed. Not enough can be said about Dr. Casselman and his staffs’ professionalism. Ash is so happy to greet each person that walks through the door and was always accommodating to my schedule, an extremely kind person. Any time I saw McKensie, I knew my treatment would be the best and I’d be back to my busy life in no time, I appreciate her hard work. Dr. C is the best! Friendly, professional, informative, genuine, and kind. From the first appointment he was honest about what he could or couldn’t fix. He was understanding of my needs and worked with me every step of the way. Can’t recommend or thank Dr. C and Pinnacle enough.

Dr. C and his team are fantastic. I had great success in correcting my scoliosis, far better than I expected, and the treatment was easier than I expected also! Dr. C utilizes imaging (so helpful to actually see my spine and know exactly what was going on rather than guesstimating like other chiropractors did) and a variety of modalities beyond just adjustments. Plus everyone on the team is so helpful and supportive. I would absolutely recommend this practice to anyone looking for holistic chiropractic treatment.

The team is very friendly and fun to work with. Dr C is very knowledgeable and personalizes care very well.

Dr. Casselman and his staff are wonderful! After years of being a hairstylist, I was having migraines weekly, and had been experiencing chronic pain for years. After only a few months of treatment here, I have only had one migraine and my overall tension and pain have severely lowered. I highly recommend if you have any spinal issues!
