    I have been seeing Dr Dagate for some time and he always seems to have my best interest in mind. He is a very pleasant person and ties to make sure all bases are checked and covered to ensure your health. Most of his staff are very nice others seem way to stressed out.

    I love love Dr. D'Agate, he is the most respected doctor I have ever had. He listens carefully and respectably and always makes sure I don't leave my appointment unless my questions are answered. I feel comfortable, and less stressful when seeing him in the Smithtown office. The only office I will go to. Thank you Dr. D'Agate and Suffolk Heart Group for taking care of me and my family..
