    This was at least my third time seeing Dr. Knapp. As always, he was extremely/genuinely friendly, knowledgeable, attentive, responsive to my inquiries and immediately prepared to provide a prescription that appears to be effective.

    Good experience overall. I like the fact that I am told of possible costs prior to treatment during the actual visit. I am not that fond of have the assistant in the room at the same time.

    Addressed concerns thoroughly and with as much or as little detail as was necessary or I requested. 10/10 would get de-moled again.

  • About Calvin Knapp III, MD

    I provide comprehensive dermatology care including the treatment of skin disease, ranging from evaluation and surgical treatment of skin cancer, to diagnosis and treatment of rashes, to general skin, hair, and nail care. The part of being a physician I love the most is when a patient tells me not just that their condition has improved, but that they feel like they have the knowledge to take care of their skin on their own in the future.

    Philosophy of care

    I believe a physician's role is to be a patient's consultant and teammate, effectively tailoring care to combine medical knowledge with the patient's priorities when creating an individualized care plan.
