Dr. Grossman has been my Dr. for over 10 years overseeing my general health issues. Whenever there is something that is out of his expertise his referrals have all been spot on with other Doctors. With all his years of experience he can usually diagnose the problem correctly for the proper treatment so the healing time is accelerated. I would whole heartily recommend Dr. Grossman.

I've been seeing Doctor Grossman for close to 30 years. He has always been very thorough during my appointments. If I have other health concerns he always answers my questions. I'd highly recommend Dr Grossman to everyone I know who needs an endocrinologist.

I not often write reviews, but because my experience was so great with Dr. Grossman that it must be shared. Dr. Grossman is a Physician that I have known for many years. I personally thank Dr. Grossman. He has been taking good care of my family. He was my Grandfather's primary doctor for more than 15 years. Now, he is also my Mom's primary doctor. He was one of the excellent doctors I knew. Dr. Grossman is very patient and knowledgeable about all questions I had. I highly recommend Dr. Grossman.

DR. GROSSMAN SAVED MY EYESIGHT. I DIDN'T KNOW I WAS DIABETIC UNTIL A HOSPITAL EMERGENCY VISIT WITH A BLOOD SUGAR LEVEL OVER 800. HE'S BEEN MY DOCTOR FOR CLOSE TO 2 YEARS. I'VE NEVER HAD A COMPLAINT WITH THE DOCTOR OR HIS STAFF IN ANY OF MY VISITS.

Dr. Grossman and his staff do not provide the customer service we expect from a specialist. My mother came home crying after her first appointment. I thought it was due to a medical problem but no, it was because they were so rude! I followed up with a phone call thinking there might have been a misunderstanding and the office staff treated me the same way. It's obvious that he does not seem to care about his patients. A one star rating is being very generous.

I've been going to Dr. Grossman for years, but each year he spent less and less time with me. He's now literally down to 2 minutes. And this last time, he was supposed to follow up with me after getting test results but never did. I called his office and could only speak with his front desk - he refused to get on the phone. I found another doctor.

The first time I saw this Dr. he belittled me, he made me to feel worthless and told be that my thyroid issue was under control and that my weight gain was because I was menopausal while saying all of this he was speaking in a loud tone almost yelling and then he asked me about my sex life!! ( which threw me off none of his business has nothing to do with thyroid) he told me to take this powder that he's selling it would help me loose weight....I now have a new Dr. that has helped tremendously!

I am satisfied with his diagnosis and treatment of medical issues. He recognized a Malignant Melanoma on my skin, sent me to a wonderful dermatologist, who did a biopsy, and a surgeon to get it removed. The team of doctors who took care of me saved my life. It started with Dr. Grossman’s fast and careful plan to keep me healthy.

Dr Grossman is well rounded, patient and very knowledgeable. He takes the time with you that you need to have all your concerns and questions answered. His recommendations are based on many different factors including age and ability to comply with a particular treatment. He takes into consideration your needs and disabilities before suggesting options. He always offers more than one option. They have had some issues with office staff in the past, their current staff is polite and respectful.
