I've been in a couple of times for Achilles issues and the treatment has been super helpful both times. Dr. C is also super helpful with at home exercises I can implement to improve my injury and he gives me every resource he possibly can.

Dr. Casselman and his staff are an articulate, compassionate, and an engaging team. Their service from the get-go is sterling. Treatments are timely and personable. My care was well monitored, and for me, personally, yielded results.

I visited Dr Casselman's office twice a week for 6 months for spine therapy, which was very beneficial. Dr Casselman provided a clear diagnosis and treatment plan and the entire team were friendly, supportive and professional. They deserve the accolades and recognition they have received.
