This is shameless self-promomotion. As I recall, Dr. Holtorf was the medical director of a chain of clinics in the US called the Fibro and Fatigue Centers. Dr. Teitelbaum replaced him in that position but I'm sure Holtorf has kept a financial interest. You'll find some posts on them here on the site. From what I've read some individual Drs. have helped people but that overall most people only lost their money and not their symptoms.
During this time I confronted Teitelbaum at a speaking engagement about his recovery rates and was told by him in front of other people that I was "very driven" and that I should "go home and examine the issues in my life." In other words, CFS was my fault.
