Dr Cahill is a great choice and the best visit I’ve had in years. He's excellent at understanding the patient and how to communicate issues. Something I appreciate after many visits with average docs.

Dr. Cahill is extremely personable and caring. He is down-to-earth and took great care in explaining how the heart works and the tests he ordered. Very nice doctor. I highly recommend him.

Dr. Cahill is one of the worst doctors I've ever experienced. This was my first and last visit with this doctor. He yelled at me for asking a question and stormed out of the room. He came back in, never apologized, and I sat there in shock and upset. I've never experienced a doctor like him. I'm still in shock and upset. I immediately came home and found another Doctor that accepts my insurance. I will never forget this experience. Unacceptable behavior for a doctor. And I know that he knows he was absolutely wrong. I complained to my insurance company also about my experience with him when I called to see if I could see another cardiologist without a referral ASAP. They were apologetic for my experience, and they weren't the ones who did anything wrong. Never ever again.
