    “This procedure [Rezum] is a wonderful alternative to taking drugs for the rest of your life. You will find Dr. Cowan’s staff to be very professional and understanding of the challenges you face with an enlarged prostate. And I will always remember what Dr. Cowan said to me as I went through testing, procedure and recovery. He said, “You may hate me now, but you will thank me later.” Well thank you Dr. Cowan, very much. You were true to your word.”— Clarke

    “Cowan is a top-notch guy. He’s got a good sense of humor and is very nice. The staff at Urology Associates was also very great. I was very happy with them and the Rezum therapy.”— Ken
