Dr. Merriam was very understanding on how I felt knowing that I have prostate cancer. He made me feel very comfortable in describing my options and going into the details so I could make the decision on my next step, I would recommend Dr, Merriam to anyone in my situation. I left the office feeling a little bit relieved. Thank you Dr. Merriam.
