During a personal crisis, this man was unreachable. My primary care physician couldn't find him in a city-wide listing of physicians, suggesting he let his license lapse (again). Dr. Greene will go on vacation and not give you a way to reach him or another psychiatrist in his absence, then brag to you about the vacation he took! On top of blaming you for missed appointments that are HIS fault. This dude is a fraud, a cheat, and a liar. Don't risk your health going to this sham of a doctor!
