Patient Forms

Very Caring, Thorough and Knowledgeable
I am a snowbird with a history of bladder cancer. Twice I had complications from surgeries in Michigan that required finding a urologist locally in Florida. Dr. Grable was recommended so I called him. His staff fit me into his busy schedule and in both cases he was able to help me. He communicated effectively with my doctor in Michigan to ensure the proper treatment. He is very caring, thorough and knowledgeable. I highly recommend him.
