Dr McKenzie is the best cardiologist I have had in my 68 years of needing one. My blood pressure, cholesterol and Tachycardia were all out of control for many years. Dr McKenzie took time to really understand the root cause of my problems and worked with me on the best solutions. He is kind and caring. He listens and explains why he is taking a specific medical position. He is simply the best!

I highly recommend him.My only concern is the difficulty in availability for an appointment. This is not unique to Dr. McKenzie. All my doctors are having this problem. It is a concern.

EKG lasted about 10 - 15 seconds. Asked Dr. McKinsey what he could tell from a 15 second ekg. His answer was it is old technology. So Why use it? (I didn't ask that). He also was going to prescribe a drug but I informed him that I was taking a similar drug. He said the Fellow had missed that and he would talk to him. Dr. McKinsey spent about 10 minutes with me and was 45 minutes late. This was not typical of my many previous visits.
