Now in my 70s I can clearly say that he is the most thorough and organized Dr. I have ever seen. The office is very responsive, schedule is typically on time, and when I had COVID the office called me every day to check on me.

I'm reluctant to rate him too highly, because I don't want him to be so busy that it interferes with the absolutely amazing care that I receive from him, but I'll do it anyway. He's almost like a concierge doctor with the level of care that he gives. He listens, never rushes me out of the office, calls or emails promptly, I almost consider him family. I'd give him 6 stars if possible. BTW, I'm a 61 year old male with diabetes, high cholesterol, hypertension, bad lungs, etc., and he keeps me in good health. Thank you Dr. Greenstein!!

Dr. G has been my physician for over 20 years. He is professional, knowledgeable and really cares about his patients. It’s also good to know that he has a solid team behind him, including a wonderful nurse practitioner. My family also became patients of his and they also hold him in the highest regard

Dr. Greenstein has taken care of both my parents and is very helpful and caring. He listens to concerns and is readily available to answer all questions. He speaks kindly to the patients and their families. He cares about his patients and their well being. The office staff is caring and knows the patient and/ or family when they call. It’s nice to be recognized as a person and not just a patient.

I have been a patient of Dr. Greenstein for over 10 years, he is a very special physician, extremely thorough, and knowledgeable, and most important is his wonderful "bedside manner". I personally have had numerous medical issues over the years, which he has always addressed, often in conjunction with my other specialists in the most professional and thorough manner. Whenever I am in contact with him he is well-versed on my medical history and my labs. His medical PA, Beth , is also excellent. His entire staff are competent, warm and friendly. When appointments are scheduled the wait time is always minimal, yet you are given ample time and never seem rushed. My wife is also his patient and fully shares my high regard for him and his entire practice. We highly recommend him. He gets 5 stars from us !

I was so happy to find Dr. Marc Greenstein. He is an excellent doctor who is kind, thorough and extremely knowledgeable. When I had my first physical with him, it was evident that he had studied my history and blood work and had made notes prior to seeing me. He is helping me keep my conditions under control which will affect my quality of life in a positive way in the years to come. Dr. Greenstein actually helped me avoid knee surgery for which I am eternally grateful. I like that he keeps up on technology and that I can send messages over his website that are answered usually in less than 24 hours during the week.

Dr. Greenstein is amazing. My husband and I have been seeing him for 15 years. He genuinely cares about his patients and never rushes our visits even though he is extremely busy. His knowledge and intelligence has always impressed me. He is always determined to find causes and solutions for our health issues. He is genuinely a dedicated physician. I feel that he has become our friend along with being our physician.
I love the access to him through his portal which you can use 24/7. He is very diligent about responding to any of my questions or concerns that I post on his portal.
His staff have been wonderful, always friendly and helpful. He never overbooks, like some of our other docs do, so we never have a long wait in his waiting room.
I can not say enough good about Dr. Marc Greenstein. I feel so fortunate to have found him 15 years ago.
