If you can get to Philly, get in touch with 3B Orthopaedics. The main location is downtown at Pennsylvania Hospital and within walking distance of public transit. Dr. Balderston did a fantastic job with my L5/S1 ADR. I don't know if he does multiple brands/models of discs but I've been absolutely loving the Prodisc he put in my spine. There are other docs in the practice that also do ADR, but I can't remember who. The facility is great though and I was glad I chose them. A lot of area athletes actually go there for stuff. I used to work right down the street from there and my manager recommended them to me. My manager actually said he saw a member of the 76ers basketball team one time while waiting on an appointment. Being formerly athletic myself, I was sold. Haha.
Good luck with your doctor search! That's a shame your local doc doesn't believe in ADR. Maybe you'll be able to shine some light on the subject with a successful ADR.
