This was my first visit with Dr. MacKenzie, and I was thoroughly pleased with the whole experience. As we spoke I instantly felt at ease; he listened patiently and talked TO me, not AT me. I also liked that he took hand-written notes instead of typing and looking at a computer while we talked. I'm very happy, and look forward to a (hopefully) long doctor/patient relationship.

The best doctor in your institution

Dr. Mackenzie is a wonderful doctor. He listened to me and provided astute perspectives/ observations. I flew from Denver where I live to see him. That is how much I value his judgement and care.

Dr MacKenzie distinguished himself by simply sitting across from me instead of in front of the computer. He is comfortable with his patients. He doesn’t need to constantly look at the computer as newer health providers seem to do. He didn’t do so until towards the end of the visit when he electronically sent my prescription and instructions in just as he described. He provided needed information about my concerns, was reassuring, was confident about how to manage a condition with my hands, was able to discuss and answer my questions, professional, kind and truly caring. I wish everyone could have the experience of being seen by a doctor with expertise as well as the manner to convey it and help his patients feel better even by the time they’re walking out of his office. Thank you Staff and Dr MacKenzie
