Dr. Yamamoto is highly skilled, and he has the most wonderful bedside manner. He has made my face look so amazing and so much younger I am delighted! I hope to see him for many years to come. Furthermore, all of the staff at Sierra Cosmetic are top notch… you really won’t find a more kind and capable team. I see Annette for all my esthetician services and she is truly my holy grail for skincare. I’m so happy I found Sierra Cosmetic and I will never go anywhere else!
