I worked in surgery for 24 years. Dr. Montazeri is one of the most skilled surgeons I ever knew. I worked in many of his surgeries and he is also my own doctor. Never knew anyone better are more skilled.

Dr Montazeri is a wonderful caring doctor. He delivered my son via c-section 28 years ago. If you are looking for a competent, caring provider, Dr Montazeri is that person.

Dr. Monte has decreased his days and hours. Disappointing, but understandable. He has worked many years. He delivered my daughter 9 years ago. I was glad to have one of the last babies he delievered. He has been my gynecologist since young adulthood, per the recommendation of my mother. I didnt want to have to start such a personal, new relationship with anyone when I moved away. Alas, I remember fondly his kindness and cool bedside manner. Also, his staff is friendly, considerate, and efficient. Also, they remember you when you go. I hate when I go to a doctor for several years and it feel like we have to be reacquainted at every visit. And it's not because he only had a few patients. They just pay attention, and that matters to me.

Morteza N Montazeri, MD, is the finest doctor I know. I have always have full trust in him, and feel there are no better doctors around. We do need more just like him. God Bless you Dr Montazeri!
