The State of New York's Office of Professional Misconduct yanked his license way back in 1994, which was only about five years after he would have completed his residency.
He had been determined guilty of two acts judged as 'gross negligence'; you can read about them here in the gory details if you want. They were both late second term abortions and high risk situations, ones which the board determined should have been done in a hospital, not an outpatient clinic.
In one of the cases, after he managed to lacerate the patient's uterus, he kept trying to remove the fetal remains, despite the fact that she had begun to bleed heavily. He wound up piercing the wall between the repro organs and the abdominal organs, damaging her intestines with his forceps to the point that she needed a colostomy. (It sounded like he had gotten a hold of them with the forceps and was trying to pull them out.)
The second woman required an emergency hysterectomy to stop the life threatening bleeding caused by cuts to her uterine artery, and cervix. It took him three hours to decide to call an ambulance to take her to a hospital.
At his hearing, he claimed to have all kinds of training, which ultimately, he had to admit wasn't exactly true.
