Patient Reviews
Oct 19, 2019
I have been going to Dr. Mark Johnston for more than 20 years and I HIGHLY RECOMMEND him. In the earlier years I was able to see him every time because his practice was growing. Now, if I ask to see him rather than a physician's assistant, his schedulers work to fit me in. Knowing that his practice has grown, if I have an illness that is temporary in nature, I will see the Physician's Assistant because whoever that is is always VERY INFORMATIVE and SPENDS THE NECESSARY TIME TO TREAT ME. I also know that this person consults with Dr. Johnston about my condition. I will rate Dr. Johnston and his staff with a 5 STAR RATING! I would do more if I could.
