Cancer Survivors Network

Hi, I am a medical student working for a family practice doctor. We recently encountered a patient who on routine examination was found to have rising PSA levels. My patient suspects that he has prostate cancer. My attending wanted to first rule-out whether or not he has prostatitis (infection of the prostate gland) before resorting to biopsy done by a specialist. My patient asked me if I knew of a good urologist. Surprisingly, my attending does not know of a good urologist off the top of his head. He asked me if I knew. Can anyone recommend a good urologist in the Houston,TX area? Thanks.
