Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

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.

I have been going to Dr. Johnston for over 15 years. He is always available every time I go and is a good and caring person. I would recommend him to anyone and I don't think you will be disappointed. He is compassionate and knowledgeable.

Avoid if you want to actually see your doctor. He is hardly in the office so you will see a different physician assistant every time. I usually end up going to a minute clinic because he’s never available.
