5.0 star star star star starDr Cohen is an honest Doctor concerned with your health and tells you what you need to do to take care of your health not necessarily what you want to hear. He wants you to take an active role in your health, he doesn’t cut corners. He takes time to explain why tests or procedures are needed and takes time to answer all of your questions.

5.0 star star star star starI met Dr. Cohen in the ER in Dec 2019 and have received outstanding care from him. At that time I ended up being transferred downtown, and was treated by many others in NM Cardiology but then resumed care with Dr. Cohen. He is straight forward, attentive, personable, amiable and makes things easy to understand even when complex. His knowledge, experience and manner elicits trust, which is crucial.
