My family have been visiting Diane’s practice for almost a decade, and she (and all her colleagues) are absolutely brilliant. My wife had quite an aversion to any dentist, as did I growing up in the UK, and Diane put that fear to bed! I can also say that she never “upsells” which many Manhattan Doctors and Dentists have a tendency to do. She is practical, kind and exceptionally thorough. And her colleagues are a pleasure to deal with as well.

I went to her as new patient as I recently moved to NyC. Never had a better, more thorough evaluation and treatment. She noticed things my past dentist hadn’t. And the hygienist was fabulous.

It is always a wonderful experience with Dr Hanan and her entire staff. I never like going to the dentist but they all make it painless and happy!!!!

My experience as a child patient of Dr. Diane L. Hanan was deeply traumatic. At age 10, I underwent a major dental surgery under anesthesia without my mother’s consent. I woke up mid-procedure, was forced back under sedation, and was discharged without proper recovery care. Multiple healthy teeth were extracted unnecessarily, something later dentists have confirmed, which has permanently affected my dental health.

Beyond the physical harm, I was treated with coldness and dismissal as a child — silenced when I tried to ask questions and made to feel invisible. The staff were aggressive during treatments, and I often left feeling hurt, frightened, and dehumanized.

Today, as an adult, I am left with lasting damage to my dental anatomy and memories of a provider who disregarded my well-being. Subsequent dentists have expressed alarm at the number of teeth extracted unnecessarily, which has permanently altered my dental anatomy and limited orthodontic treatment options as an adult. I continue to suffer both physical and emotional consequences. Today, the unnecessary extractions limit my orthodontic options and serve as a physical reminder of that trauma. I want to acknowledge the harm, honor my younger self, and recognize that I deserved better care and respect.

I share this to warn others and to give voice to what I could not say as a child: this was not care, it was harm.

Always impressed with the quality of the work done. I have had everything from a simple filling to complicated implants. Always receive great work, awesome staff, and timely appointments and no delays in office.
