  • Dr McGahan is an artiste. My sciatica is gone. I trusted him the first day I met him. I was afraid of spine surgery but if you must have it done, I highly recommend him.

  • Dr.McGahan is a phenomenal surgeon. He did a microdysectomy on me one week ago today. I had been in pain for a year following a car accident. Immediately after surgery the nerve pain was gone and I am finally feeling like I will get my life back. I can not thank him and his surgical team enough. I hope to thank him in person at my next post-op.
