Clean office with excellent staff. The doctor was knowledgeable, kind, funny and attentive. He ran the appropriate diagnostic tests to put me at ease and suggested a follow up stress test. His echocardiogram technician was very kind and thorough as well. Doctor reviewed results of test same day and was extremely patient, answering all questions asked.

The office is very clean and the front line staff is very professional and kind. Dr. Mayer needs to learn how to speak with his patients and not talk down to his patients. Im not sure if i will be returning because of this.........

Very knowledgeable and helpful to speak with, even when it turned out my issue was likely GI related rather than heart related.

January 25, 2021Yelena F.Verified patient
My cardiology consultation with Dr. Mayer was excellent. He took time to understand my medical history and symptoms and gave detailed answers and explanations to all my questions. He made me feel comfortable and confident about my plan of care -- I feel like I'm in great hands. Highly recommend!

Dr. Mayer is fantastic. Listened to everything I said, gave me some honest and welcome feedback on some of the dumber things I said (lol), excellent bedside manner and legitimately cared about finding the source of my issues. Wish he could somehow also be my PCP because of all the random specialists I've had to see lately he's by far the most sane and thoughtful one of the bunch.
Also I went to both his locations (Greenpoint and Queens) and in both cases the offices were clean, well-equipped, and the staff was friendly, professional, and very caring.
Great practice, definitely recommended.
