I was diagnosed with type 1 diabetes (LADA) and she rushed to put my on insulin when there was little urgency. She had my dosages way too high. Very self centered doctor and cares more about covering herself than the patient. Not sure how she's going to make any money now that she doesn't take insurance. Stay away...dangerous!!!

I was referred to Dr. Messer by my primary care physician. She was great, friendly, attentive, just excellent! I'm sorry that she will no longer be accepting private insurance. The downside was the wait of 3 months for an appointment and the office staff!

Dr Messer is the most compassionate, competant endocrinologist doctor. She and Brittany who runs the front office are an incredible team. This is a wonderful place for endocrinology. Sorry they no longer take any health insurance and aren't apart of Lenox Hill hospital. A big loss for patients...

Dr Messer could not diagnose or treat me properly. She prescribed medicine for Type II diabetes while I am an adult I. She made me sicker. . She also brought a Duke college student into my examination. She did not say the student was not a medical student. I felt extremely embarrassed speaking in front of a college student and unsure of the confidentiality. This woman is self-centered and dangerous. She no longer accepts insurance and I wonder why.

I saw Dr Messer today for the first time. I was SUPER IMPRESSED! She was VERY thorough, listened and explained everything. She even showed me pictures explaining what was going on in my vody. For a change I didn't feel rushed. Towards the end of my appointment she asked me if I understood everything that was mentioned. Wished I would have seen her sooner. Soooo happy I went there for a second opinion. She picked up on things that my prevoius doctor never did. She is officially my new Dr.

Dr. Messer is a great doctor. She is friendly, professional and listens well to address my concerns.
in New York, NY |
Dr Messer is only interested in conducting tests and then referring the patient to another doctor. She has no interest in the patient's overall health and well-being. Her delivery of test results is nothing short of brutal.
