Dr. Berson is a very petty doctor. If you have to cancel, make sure you do it in 24 hours. He sent me to a collection because I didn't give him a 24 hour notice. I gave him 21 hours’ notice, but he is so trivial that he had to send me to a collection agency. He was also not a very friendly doctor. I didn't find him helpful because he repeated himself quite frequently. The services were for my daughter and she didn't feel comfortable with him at all.
