Alex Guerrero, according to a January
story in the New York Times, is
New England Patriots quarterback
Tom Brady's "best friend and ever-present guru for training and many other things." He has been referred to in various articles as Brady's "body coach" and, according to the
Times, can more accurately be considered a "spiritual guide, counselor, pal, nutrition adviser, trainer, massage therapist and family member."
According to a report from
Boston Magazine, Guerrero used to go by the name Dr. Alejandro Geurrero and was investigated by the Federal Trade Commission (FTC), twice.
On the first occasion, in 2004, Guerrero was part of an infomercial for a product called Supreme Greens, which claimed, among other things, to be able to cure "ailments such as cancer, AIDS, multiple sclerosis, and Parkinson's disease." A study was conducted on 200 patients, the infomercial said, and all but eight survived. The FTC debunked that claim and others made by Guerrero in the infomercial -- including the fact that he was a doctor -- as a sham.
