OJ is excellent at what he does. He has done a great job addressing all of my skin related issues over the years! One visit awhile back, he finished a proceedure and as he departed he said to me, "John I'm going to do my best toShow more keep you alive!" He is doing just that and I so appreciate him! He is kind and funny and serious all at the same time. His rapport with patients is second to none!
