Ronald Yamaguchi, MD

Urology

Welcome to My Doctor Online, a website that my colleagues and I have developed to make it easier for you to interact with me and for me to take care of your healthcare needs. You can e-mail me, check your lab results, make an appointment, access our many online programs or get information about a particular health topic - any time it's convenient for you. I'm eager to work with you to make your experience at Kaiser Permanente a positive one.
