Dr Mezei is a very caring cardiologist and spends time with you to explain tests, diagnosis and treatment. I find him to be an amazing doctor and so glad that my primary doctor recommended him to me. Dr Mezei will make you feel like you are his only patient. Another plus is that the staff is also incredible...very kind and caring! My heart is in great hands!!!

I would recommend Dr. Mezei without any reservations. He is courteous, but he is thorough in his discussion of his course of treatment. I fully believe that through Dr. Mezei's competent and insightful knowledge, he diagnosed my medical condition and through his course of treatment, I avoided further serious medical issues.
