She is the absolute best! I’ve been coming to her for a long time now. Before her, I had many endocrinologist, none of them as good as Dr. Katz. She listens, and she cares.
July 5, 2019Ayelet M.Verified patient
She was great! We spent almost an hour talking about my history for my first appointment and she really took the time to ask questions and listen to me. I never felt rushed at all, unlike I’ve seen from other doctors. After the questions, she went to examine me. She was very thorough in her explanations for my questions and the best part is that she offers extra information. A lot of the times doctors don’t explain everything and never gives any extra info,, but she really goes into detail and I really like that. I feel like she cares. Dr Katz also offered me realistic expectations for my treatments and also told me from her experience what worked and what didn’t. I’m really glad I found her!

Dr. Katz is one of those patient, understanding, down-to-earth gems that you search for in a new doctor. I came to her with a laundry list and she listened - never interrupting - and helped me formulate a plan to tackle symptoms of PCOS in a careful and realistic way. I have gone back for a follow-up and was impressed again at the instant rapport and feeling of confidence that I left with. I couldn't recommend her more highly.
More than 1 year agoEmily S.Verified patient
This doctor was excellent. She really spent the time with me to go over my medical history and concerns. You can tell that she really cares about her patients and finding the root cause of the problem and the best way to address it. We discussed multiple solutions, including dietary, lifestyle and pharmaceutical ones that may help me address my problem. I look forward to my next appointment with her!
July 2, 2018Patricia V.Verified patient
I enjoyed visiting Dr. Katz. She is a pleasant person to talk to and knows her area of expertise very well. I will stay with her in the future.
June 18, 2018Radisav C.Verified patient
Dr. Katz and her staff were warm and welcoming, and I was seen right at my scheduled appointment time. I felt like Dr. Katz really listened to all of my concerns and was very communicative about what she thought was going on and how best to treat my issues. The office was very clean and modern-looking and easy to find. Would definitely recommend!
January 16, 2018William P.Verified patient
After seeing another endocrinologist whose practice was a total disaster, I switched to Dr. Katz based on many good reviews online and I was not disappointed! Her manner was excellent, very straightforward and easy to talk to. She gave me a thorough checkup and good information about my condition. The wait time in her office was about 30 minutes past my scheduled appointment time, but the receptionists were helpful and gave updates about how long the wait would be. I will be continuing with her and I would definitely recommend her to others with a similar condition.

April 8, 2016Kathleen M.Verified patient
She is the nicest doctor I have ever met so far. I have had my fair share of endocrinologists and I honestly have not met anyone that cared and that is as friendly as Dr. Katz. She always makes you feel comfortable and makes you feel like things will be okay and that she is always always whenever you need her. She is just overall a really great doctor and I wish that there were more like her in the medical field.
More than 1 year agoYoumna E.Verified patient
Dr. Katz was very pleasant and professional, and the same applies to her staff. I did not have to wait long at all, and for once I managed to complete a doctor's appointment within my lunch hour!
As one would expect, Dr. Katz was very knowledgeable about my condition, and she knew the best doctors in New York to treat its related conditions as well.
