A man impersonating a clinical psychologist treated over 100 people in his basement where he also prescribed antidepressants.

On Thursday, Donald Lee-Edwards, 43, plead not guilty to criminal impersonation, drug sale, scheme to defraud and other charges, according to ABC News.

Lee-Edwards was is a former flight attendant who began treating patients in his makeshift office in the basement of his Staten Island house that he lives in with his parents. The home was found to be outfitted with multiple treatment rooms, a waiting area and also high-tech security equipment.

Reports stated that he met with patients for up to two hours at a time. He also gave out fake prescriptions, often calling them in directly to pharmacies to avoid having to use a state-issued prescription pad.

He also allegedly called in prescriptions specifically for generic medications to sidestep having to enter them into the database that doctors use to prescribe controlled substances and pharmacists also use to track the prescriptions.

“This so-called ‘doctor’ is a dangerous scam artist who never completed any medical school or doctoral program,” Acting Richmond County District Attorney Daniel Master Jr. said. “He merely bestowed upon himself the professional titles of clinical psychologist and medical doctor; he is neither trained nor licensed to provide any mental health or medical services.”

But his defense attorney, Matthew Blum, argued that Lee-Edwards never harmed anybody.

“They’re alleging he was some sort of doctor who was operating on people,” Blum said. “They’re turning this guy into a monster. He was really just trying to help some people in his community.”

There is no evidence found so far that Lee-Edwards attending any medical schooling.

The investigation was sparked when patients back in June started to tell authorities about Lee-Edward’s unusual bedside manner which made some patients wonder if he really was a doctor at all. The suspicions started when Lee-Edwards was noticed to often talk about other patients personal “cases” and told unbelievable stories about graduating high school at the age of 13 and also attending law school.

Investigators found medical equipment, dozens of blood vials and an identification card that was homemade when they searched his office. Lee-Edwards, if convicted, will face up to five years in prison.
