I look forward to my visit with Dr. Zachary every time. I went in there feeling stressed out and not feeling well, but by the time I left, he had calmed me down. My blood pressure went down and I felt a lot better. He takes the time to listen and helps with his talk and his examination and then follows up right away with anything that needs to be followed up with.

I was referred to Dr Zachary for second opinion re a bad invasive MAC germ in my lungs. Although it is depressing to hear about the unlikely cure the heavy and expensive drugs that might help somewhat instill feelings he is one of the best ID docs to see and discuss the options.

Hi, Dr. Zachary has always been great. I think 2019, he goes above and beyond with listening, explaining things, ordering things, and when something does come up that needs to be looked at, he's right on it right away and follows up and very pleased. He's the best.
