This review is reflective of the entire team at Chico Dermatology. The reason is that on Monday I did not have an appointment be had a spot develop on me hand that had become what was suspected as a Squ…..cell carcinoma. I called Show moreto make an appointment but it was going to be a long time for an opening for an appointment. Instead the receptionist said to come in and a PA would take a picture and refer it to a doctor to evaluate. We were coming to Chico on Monday so stopped in. Once the pic was taken, she took it to Dr O Jay. Before long he came in with assistants and said we need to do a biopsy. This was done. So I was very grateful for the team to get things underway the same day I called. Noe we wait for results of pathology.

O.J. and his staff were very friendly, inviting and knowledgeable. The facilities were beautiful and very clean. Recently, my grandson had a skin problem, so O.J. squeezed him into the schedule to care for him. I feel like they knShow moreow me well and take good care of me.
