Dr. Ryan has a remarkable memory of my health issues and preferences. He is an excellent doctor.
Dr. Ryan is always well informed about my current health including any recent tests. He always asks detailed questions about issues directly related to my heart. His advice is obviously not just based on formulaic medical protocol; he uses years of experience to discuss different options for treatment and answers questions factually while acknowledging that each patient's experience may be different. I trust his advice and have followed it to achieve health results that I believe many other medical professionals -- especially Cardiologists - would have not believed possible.
