    Dr. Breyer is indeed an outstanding surgeon in his field of specialties. He was kind and understanding enough to accept to see me and do the procedure himself. In addition, he reviewed my MRI Images and radiologists' reports on an emerging mass on my left kidney. He performed an exceptionally expert procedure on me with no pain, discomfort or complication and made it much more easier than I expected. Dr. Breyer shared the result with me, explained options for treatment of OAB , included my preference in choosing the option, explained clearly the instruction.Above all, Dr. Breyer referred me to one of the best and most experienced urology oncology surgeons at UCSF , Dr. Oshido, for review of my kidney case and treatment proposal. In short, Dr. Breyer is outstandingly expert in his fields of specialties, impressively knowledgable, very caring of his patients, very friendly , and a most valuable asset to the UCSF urology department. I am so happy and privileged to be his patient. Thank you Dr. Breyer!
