Dr. Kerwin was seriously amazing! He had the best bedside manner and actually took the time to listen to everything I was saying. He was so quick to understand my concerns and went over all the different options with me, including the pros and cons of each, instead of just telling me what to do. I never felt rushed or dismissed at all. He was very knowledgeable, honest, and made me feel completely comfortable with the plan we decided on. I’m honestly so happy I saw him and would definitely recommend him to anyone

Leonard Kerwin was absolutely excellent! He removed a cyst from my scalp, and I couldn’t have asked for a better experience. He was professional, knowledgeable, gentle, and took the time to explain the procedure and answer my questions. He made me feel comfortable and confident that I was in good hands. I truly appreciate the care and kindness showed he me throughout the entire process. I would highly recommend Dr. Kerwin to anyone looking for an excellent dermatologist! ❤️
