Patient Testimonial

Atlantic is top-notch! After breaking my leg a year ago and being treated non-operatively and having continued pain. They were able to get me in to see Dr. McMahon quickly who ordered an MRI which was done the same day in the office at Shields. I followed up with Dr. Welch who was great!  I had surgery and am now feeling much better and well on my way to recovery and skiing this winter!
