How likely are you to recommend Dr. Dongas?

(Select your rating)
Dr. Dongas has been our family's cardiologist for years. When I started to have symptoms, I can tell you that at least 3 other doctors told me it was "my age and change of life." Well, no. It was a severe issue that, had I not seen Dr. Dongas, would have caused a massive stroke. His bedside manner is matter-of-fact. He doesn't sugar-coat. He tells me what I need to know, I ask questions, and he answers them. I felt that my heart was in good hands; I'm "fixed" now, and I recommend him highly.
