I went to the THC Foundation this last week, and they were wonderful. I had faxed them my medical charts, and they called back the same day...about 30 minutes later, in fact...to tell me that everything looked great. I set up an appointment and went down to fill out some paperwork and meet the Dr. I was in and out in about 1 hour and 15 minutes. I paid them $180 for the signature...and that leaves $90 for the registration fee. It was cake, and they were wonderful to work with. The downside being that it costs an extra $200 ($180 if paid in advance) for the signature. It would be cheaper to go to your primary care doctor...but I just didn't want to go there with mine.
