Guerrero is a controversial figure. Once accused of falsely presenting himself as a doctor, the 52-year-old has reportedly drawn ire from those within the Patriots organization for his alternative treatment methods.

While Guerrero treated Patriots players and other TB12 clients there, investigators looked into allegations that he was practicing physical therapy without a license. State regulators in MA also intervened, believing he was practicing physical therapy without a license.
