Action News Now found several documents from the Medical Board of California charging Dr. Larry Pyle with improper physical contact with a patient as well as gross negligence.
Pyle is currently facing charges for aiding or abetting in the unlicensed practice of medicine.
The Shasta County District Attorney's Office says Pyle provided Susan Tancreto with Botox which she then illegally injected into clients.
But according to documents, Pyle has a long history of misconduct.
His first misconduct charge dates as far back as 1997.
In 2014, his license was revoked for sexual misconduct.
But he was allowed to continue practicing medicine as long as he agreed to be on probation for three years and took an ethics course.
In 2016, his license was revoked again for gross negligence.
But the decision was stayed pending he agreed to go on probation again, this time for seven years.
Pyle was also licensed to practice medicine in New York state, but was forced to surrender his license in 2016 after the New York Board for Professional Medical Conduct caught wind of his misconduct in California.
