Read what I wrote in response to the first question about my 25 years as a patient with Dr. Yamamoto. He is a skilled, caring, and personable professional. he deserves a raise. So do Dean and Hilda on his staff.

I see doctor Yamamoto every 6 months after having a melanoma long time ago. He usually takes less than two minutes to look at my skin and doesn't do a through exam. There are many areas on my skin that doesn't get looked at so I am never sure if I may or may not have melanoma. I understand that I am at lower risk now because of the time passed after my melanoma diagnosis, but I still expect at least to have a through exam. My previous doctor used to take a long time to look everywhere including inside me ears, toes, head and every where else with a scope and had an assistant with him too. None of these things are done now.
