I went there for a short time before I moved to Naples. It was okay but at that time (over 6 years ago) they were overwhelmed and short staffed. I don't think that is the case any longer.
FYI-The Accelerated Cure Project and The Ohio State University now have a repository at OSU. The information is:
The Ohio State University Medical Center
Multiple Sclerosis Center
1654 Upham Drive, 445 Means Hall
Columbus, OH 43210
Principal investigator: Michael Racke, MD
Study coordinator: Lisa Hafer
Study coordinator phone: 614-293-7877
Study coordinator e-mail: firstname.lastname@example.org
If I were in Ohio now I would definitely make an appointment at OSU. There seems to be quite a bit of research going on.
BTW When I come to Columbus this summer I am planning on going into the the center to donate into the ACP repository. I was never able to do so before as there were no centers anywhere close to me.
