I was seen by the medical student working with Dr. O'Riordan before he came in the room. She was professional and covered everything she needed about the reason for my visit to repeat to the doctor when he came in. He listened to her and confirmed with me what she was saying. He asked if I had anything to add or any questions. I felt that I had a complete exam.

I like Dr. O'Riordan very much. His manner is upbeat and cheerful and I think that's the best kind of personality for a heart doctor because heart patients have a lot of fear and stress about their condition and his manner is very uplifting.
