Having had 3 anterior cervical fusions, and 1 anterior lumbar fusion I've had a lot of good and bad experiences with physical therapist over the years.
My experience with Impact Physical Therapy has been a positive one. What sets them apart are the talented and experianced physical therapist that work with you. Unlike many PT shops you are with a doctor of physical therapy (and not a tech) the entire time!
I've had the pleasure of having been seen by three of their doctors (Eric, Dave, and Sara) over the past 5 weeks and I can say that I feel much stronger and have much more more range of motion than when I started. I'll be having major posterior cervical surgery in a couple of weeks and these sessions at Impact have been an immense help in preparation for that surgery.
