Patient Comments (6)
in Marlboro, NJ |
Probably the most disturbing doctor experience i've ever endured. He was extremely condescending and made assumptions about me without hearing my background history. Wouldn't listen to anything I had to say and only wanted to make his own judgements. Spent an hour with me but he talked 80% of the time. Here is my fair warning, do not visit this endocrinologist. Didn't even answer my last email, waited 3 weeks. Went to him because he's fairly young and thought he'd be nice a guy, I was wrong.

I work in the healthcare field, and unfortunately have many specialists that I see regularly for ongoing care. Dr. Ausiello is the most dedicated, honest and thorough doctor I have ever had the pleasure to know. He genuinely cares about his patients and their well-being which makes him very passionate . I am lucky to be under his care!

He is, by far, the best doctor. He is caring, thoughtful and extremely professional My mother is a difficult patient. She doesn't follow doctor's instructions, but he has made her a better patient. He is firm in his directions, but kind. I love him.
in Bronx, NY |
I saw Dr. Ausiello after being diagnosed with Grave's disease in January of 2017. Initially, Dr. Ausiello was kind and explained my condition well. Each subsequent appt/interaction with Dr. Ausiello became increasingly disturbing and by the 3rd visit, I decided to seek healthcare elsewhere. Dr. Ausiello consistently dismiss all of my reports of symptoms as having *nothing to do with the Grave's disease or the medication I was on* he also became overtly hostile, even yelling at me over the phone.

Dr. Ausiello was so much more than I ever expected . He was caring, compassionate and a great listener. I am so thankful to have found him . Also, he's not an alarmist and very comforting . Super competent, and thorough - best decision I've made .
