Had an excellent first experience with Oak Derm today. I was seen by NP Emily Schnurstein for facial flushing and hair loss. She listened carefully to all of my concerns and addressed each one of them throughly. The front desk staff was also very pleasant.

Yesterday I had a fantastic skin check and initial visit with Dr. Janiga. From the moment he stepped into the exam room he made me feel comfortable, was extremely personable, and helped educate me about caring for my skin and skin health. I enjoyed his approach of checking me over interspersed with talks about what he found/how I can continue to care for myself. Working in a medical role I interact with all sorts of doctors regularly and can say he is the best combination of professional and casual. Oak Dermatology’s entire staff was also helpful, friendly, and patient while providing a clean and tidy office. I will go out of my way to make sure I continue seeing Dr. Janiga in the future for my check-ups and will recommend him whenever given the chance.
