Dr. Montazem is a very caring and professional Doctor. I had work to be done that I put off for a very long time and was very nervous. I felt comfortable in the office from the reception desk to the procedure room. I would highly recommend Dr. Montazem to anyone and everyone..

I went to Dr. Montazem to have my wisdom teeth removed. I would absolutely recommend him and his team to anyone looking for an oral surgeon in the area. Dr. Montazem made the whole experience of having a procedure painless. I get anxiety when it comes to any type of surgery but him and his team made sure I was completely comfortable and understood all steps of the procedure and recovery. Everything was done with little or no pain for me!

I have been a patient of Dr. Montazem for quite a few years. I have needed to have quite a few teeth extracted and at least five dental implants done. Dr. Montazem and his staff were wonderful! I also had all three of my daughters wisdom teeth extracted by Dr. Montazem when they were in their teens. He was terrific with them! I always recommend Dr. Montazem to anyone who needs an oral surgeon!
Middle Village, NY |
Dr. Montazem is a very unprofessional doctor. He is rude, condescending and short. My son was saw the doctor to have wisdom teeth and Dr. Montazem spoke to my son as if he was stupid if he didnt do the procedure and gave brief answers to questions. His office never picks up the phone and when you finally get someone on the phone they too are rude. It is unbelievable that a doctor and his staff operate in this manner!
Ronkonkoma, NY |
I tried to set up an appointment w Dr. Montazem but a woman receptionist refused to do it simply because I did not provide details for the need to see doctor for dental problem I have. The receptionist on the phone was very rude and unprofessional. I explained that I need consultation and second opinion but she insists on asking HIPPA information which I did not want to provide over the telephone. She just hung up on me. \
St James, NY |
I would not recommend this oral surgeon to anyone. He has a real bedside manner, along with his staff and additionally charges higher than any other oral surgeon in the neighborhood.
