I have been with this doctor for over 3 years visiting often for a rare kidney disease and I have never had a bad experience with him or his staff.

Dr Johnston is absolutely the BEST doctor I have ever experienced!!!

April 16, 2019

I have enjoyed wonderful care from Dr. Johnston for 29 years and wish him well in his retirement.

First of all, Dr. Johnston is the best you have. I can not say enough good things about him. He only goes over my meds, that we have discussed, after I have blood which is every two months. I receive my blood results from you on the internet, and I log them on a spread sheet. If and when I would have a concern about either medication or blood results, I have no problem contacting Dr. Johnston through this system, and he answers my e-mails when he has time, unless it would be an emergency, then right away, and I do understand that. Like I said, Dr. Johnston is kind, knowledgeable about this field and others, always there for me, and I know how fortunate I am to have him as my doctor. I always look forward to seeing him twice a year!!!!!!!!!!!!!!!!!!!

Dr. Johnston is, by far, the best doctor I've ever had. He treats his patients with care, interest, and respect. He is truly one in a million.
