What Our Patients Say

Susanne Lockhart, MD
5 Stars  I’ve been a patient of Dr Lockhart’s for ~ 20 years and she is always friendly and very thorough. I’m confident if I have anything serious or any skin disorder, she’lll find it and take care of it. Many years ago, she found a basal cell carcinoma beside my right eye. We had it removed, which was painless, and have had no issues since. I’m so thankful that she noticed it. I see her every year for a check up. Everyone, especially those of us who had sun exposure during our lives should see a dermatologist and you won’t find anyone better than Dr Lockhart and her associates. They are all excellent. It’s a good feeling having a doctor you can trust 100%. –

5 Stars  Dr. Lockhart is thorough and not aggressive in taking "samples" of every skin blemish that I've found other dermatologists doing so. Office staff is very efficient...quite satisfied. –
