Excellent staff, excellent doctor! I was blown away by how quickly I was seen and how knowledgeable the doctor was. He was very thorough, asked detailed questions, and I love that I will have access to my bloodwork results immediately throughtheir online portal. I also appreciate that the doctor provides his e-mail address for any questions. Really great service.

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...

I've been seeing Dr. Gruenspan for about five years, initially for a thyroid problem that he has kept under control. Over the years, he has become my go-to doctor for a whole range of problems. Dr, Gruenspan is extremely knowledgeable, careful,supportive, and warm. Similarly, his office and nursing staff are first-rate.

Dr. Gruenspan's office is GREAT! Danielle at the front desk is a sweetheart. She is very accommodating, helpful and caring. Lisette (I believe this was her name who took blood) was gentile and talked me through procedure. Dr. Gruenspan is verypatient when getting to know you. He is thorough in his evaluation and listens to your concerns. He also referred me to an amazing radiology place (Lennox Hill) so his affiliates are just as great. I am lucky to have found this Dr. He and his staff are angels! I would refer this office to anyone and everyone! Stellar!

Everyone in the office is very nice! The last time I saw Dr. Gruenspan was 4 years ago and he acted as if he remembered my entire health history (even though I'm sure he had just scanned my file quickly beforeseeing me). He genuinely listened to me and made me feel optimistic in finding out and fixing what is going on. Highly recommend.

GREAT!!! My experience with Dr. Gruenspan and his staff was beyond amazing!! Dr. Gruenspan spent a good amount of time with me which really surprised me; not a lot of doctors spend a good amount of time with you. He tookhis time to listen to me and gave me such great advice. He did not rush me which makes me feel like he was really listening. He was very calm and had a great smile! Not to mention VERY smart. I knew I was in good hands. They take the blood in the office(which is a plus) and the nurse was very gentle and caring....didn't feel a thing. The young lady at the front desk was great; from check in to check out she had a smile and made me feel so comfortable. Making him my PCP. To sum up my experience with Dr. Gruenspan.... IT WAS GREAT!! I DEFINITELY RECOMMEND HIM!
