I did not have serious problems when I went to Dr. Casselman but problems that had persisted for years. After completing my time, I can honestly say that my back and neck feel much stronger and my ankle, that had been giving me lots of problems, is now almost problem free. Dr. Casselman listens to what you are telling him about your body and then works to fix the problem(s). The exercises that he has you do help your success and they have been very beneficial for me. Once your program is done, he also sends you home with exercises so your progress will continue even though you are no longer at the clinic. I am so thankful we found Dr. Casselman on the internet and I highly recommend him if you are having back, neck, or feet problems.
