Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Dr Cohen is a wonderful doctor. He is very knowledgeable, kind, and puts patients at ease. It is easy to contact him if needed and he always is attentive and answers promptly.

I had a colonoscopy performed by Dr. Cohen. I found he was professional and personable. He made me feel comfortable before and during the procedure. He even called the day after to ask how I was doing. I would definitely recommend him. My only negative comment about the practice has to do with his nurse, Maritza. She phoned the prep prescription to 2 different pharmacies. One of which was a mail order who automatically mailed it out with a much higher price than the local pharmacy. I am now dealing with having to return it. She also demanded my credit card information without telling how much I would be billed for Dr. Cohen's services. This was before anything was submitted to my health insurance. I advised her I would wait for a bill/statement before providing that information.

I absolutely recommend Dr. Cohen to my family and friends. He is a great listener and communicator. To me, he is the very best in his field as he is knowledgeable, experienced, and savvy in technical skills. He is my "go to" doctor as I have complete trust in him. He is quick to respond to concerns and always displays caring and compassion. You cannot go wrong with Dr. Greg Cohen.

I have seen Dr. Cohen several times over the year and he had done colonoscopy and endoscopy procedures on me as well. Dr. Cohen is an outstanding and rare kind of doctor. He comes into an appointment fully prepared from reading a patient's records and then spends a lot of time asking questions and actually listening to help the diagnostic process. He spends more time with patients than any other doc I have seen (minimum of 30 minutes), and really cares about them. He obviously is highly experienced and is an excellent diagnostician. He presents treatment options clearly and explains the pros and cons of them, then letting the patient decide on an informed basis. He is state of the art in following new developments and treatments. He is also a great person. Maritza, who manages his office, is very kind, supportive and helpful. Overall, I could not be more pleased with Dr. Cohen and his practice.

Patient for 16 years. Dr. Cohen is extremely professional and knowledgeable. He is compassionate and really cares for his patients. He is up to date and participates in the most current research. I was really sick three years ago during the Christmas holiday, Dr. Cohen was with me every step of the way and reassured me that I would recover. He told me to call whenever I needed to ask a question or I was concerned, and needed reassurance. This included Christmas Eve and Christmas Day. He responded to my calls within 30 minutes and spent time speaking with me, it meant a great deal. He let me know that he cared and that I was not a burden. Now that I am recovered he continues to show me the same compassion and provides me with same great care based on the current research. Maritza, his Administrative Assistant is wonderful! she is very kind and professional and remembers patients. She takes an interest in the patients and truly cares.

He is extremely thorough, does not make you feel rushed and spends as much time as needed to go over symptoms, background and treatment options. He also speaks in laymen's terms when explaining anatomy. His assistant Maritza is great about getting right back to you and both of them are very accessible.

Dr. Cohen was fantastic to talk to and was very focused and responsive to the GI issues I was having. He was very personable and I never felt like he was going through the motions or wanted me to leave his office. He explained his thoughts on what may be causing my issues and what the procedure would entail. He reinforced at the pre-meeting, prior to the actual procedure and in his report out message to me how he and the team would take good care of me and if I had any questions to let him know. I would highly recommend Dr. Cohen to any of my friends or family.

During my appointment with Dr. Cohen, he was very knowledgeable. He asked me well thought out questions to determine how he could best help me with my stomach issues. After he finished asking me a series of questions he put together a 4 step action plan. This is how a doctor is supposed to treat their patients. With care and compassion. I was really impressed. Also the lady who checked me in was so professional and kind. I would highly recommend Dr. Cohen to my friends and family.
