I have bi-yearly skin checks with Doctor Johnson. Occasionally, I need to see her in between appointments due to a new skin issue that concerns me and would not keep until my regular scheduled visit. Her office is prompt in setting an appointment, usually within the first week of my call. Doctor Johnson is thorough in exams and provides the necessary treatment to resolve the skin issues that are specific to my issues.
