I walked into OJ's office without an appointment, hoping they could squeeze me in. I was having pain on the left side of my face and a terrible skin condition that was making me ashamed TO BE SEEN IN PUBLIC. To my surprise and deShow morelight, they'd just had a "no show," and were able to get me right in! I did not have what I thought I had (we love to research our own medical conditions on the internet, don't we?), but OJ quickly diagnosed my skin issue and prescribed medicine to treat it. I'm so grateful to OJ and his wonderful staff, and to the "skin angel" who was sitting on my shoulder that day.

Ojay has always been a great provider for finding my pre-cancerous spots even before I know where they are. Ojay always makes the visit a pleasant one. It’s always a learning experience for me as a patient. He teaches me new thingShow mores new ways to look for the spots that could be harmful if left untreated. I never think about going anywhere else besides Chico Dermatology. Tom Reese
