    Dr Onal was the first doctor I've had who has taken the time to listen to me and explain everything thoroughly about how I can improve my health and my symptoms. He was very kind and compassionate and I feel relieved after having my appointment with him. For t he first time in a Long time, I felt like a doctor actually listened to me. As for the nurses and office staff, they were all incredible. Every one of them. I wish I could remember names specifically but they were friendly, helpful with my children and the overall experience completely exceeded all of my expectations. Thank you to this wonderful team of caring and compassionate people.

    Dr. Onal is a fantastic cardiologist. I especially appreciate his willingness to explain exactly what the findings mean, and why certain “abnormal” findings are actually normal, so I am equipped to address those concerns with other practitioners in the future.
