Testimonials Hear from Patients and Professionals: These folks are incredibly well trained! In my experience I have just seen the product that comes out of C. H. Martin is… The best! We started using C. H. Martin Services and they are great! To anyone who is in need of prosthetic or orthotic braces, they are by far, the best that I’ve experienced. They were confident in what they were doing, and that was displayed in their knowledge and the techniques they were using.
