I've been seeing Dr. Kornu since 2015- he's an amazing doctor. He's extremely thorough and detail oriented, and listens to every symptom, big or small. I wouldn't recommend any rheumatologist but him- plus his staff (Olivia at the front desk, Jackie the nurse) are just as friendly, caring and knowledgeable.
