While there was a wait time, Dr. Gruenspan was well worth it. He has evening appointments and I had the latest time slot. After years of medical problems and frustration around receiving no answers, Dr. Gruenspan got to the bottom ofit- and quickly. He listened attentively as I listed every ailment. He ran a ton of tests (all the right ones apparently) and I was able to view these on the portal. As soon as all the results were in, he contacted me (on a Sunday) and sent me a follow up plan. I’m so relieved to have finally found an endocrinologist I can trust. Would highly recommend!

Dr. Gruenspan has an amazing bedside manners with calming presence. He took a detailed clinical history, stopped to clarify and get more details when there were significant observations, and did a thorough clinical examination before referringme to lab tests. The best clinical experience in the past 10 years of my life in USA.

Didn't have to wait more than a few minutes. Dr. Gruenspan was thoughtful and thorough, and it's clear that he keeps up with current medical research to inform the plan of care. Better experience than visits with my past endocrinologists.

Great Experience. Dr. Gruenspan really took an individualized approach. He reviewed my whole history and ordered necessary additional labs to get the complete picture. He went through the pluses and minuses of different treatment optionsto figure out what was best for me. He has a wide breadth of medical knowledge. I'm glad to have found him.

Do not see this doctor. The wait to first see him was so long. Then they said I was going to get blood drawn right away and that was another 30+ min to wait. Then when i finally got my resultsand recommendation for a medication, I followed up with some questions (at least 3 follow ups). It took him a whole month to get back to me and still hasn't filled the prescription. Worst experience ever.

I was disappointed after seeing all of the positive reviews on Zocdoc. I felt like the doctor was unsure about how to treat my previously diagnosed Hypothyroidism. It was somewhat difficult to get him to talk about my condition.

He's very thorough, and as a new patient, that was important to me. Pay attention, as he is a little soft spoken ;-)... After 30 years with my prior Endo, it was a pleasure to find Dr. Greenspan to be so facilitative in making this an easy transition!

By far the worst experience I had. Dr. Grunspan diagnosed a new chronic medical condition that requires treatment and care as I have never had it. Not only did he gave me the news about my condition via email, he didnot answer my questions and follow-ups until this day. It has been roughly 5 months...
