After suffering with incontinence for 10 years after radical prostectomy I am completely dry and can lead a normal life. Doctor Knoll did a procedure on me and has been a real life changer for me. What a blessing when I found him .

After 10 years of total incontenence following radical prostate surgery Dr. Knoll did a procedure that has been an amazing success. I am totally dry. What a blessing.

Mayo Clinic recommended Dr. Knoll to me because he was excellent in their opinion and much closer to me than going to Mayo. He has been wonderful, knowledgeable and taken care of me and my wife also. He treats you as a person, very caring and explains everything. He makes you feel comfortable to ask instead questions rather than being insulted like most doctors seem to be. He truly is very busy but takes the time for you. He is just wonderful about explaining everything and his staff is outstanding also. He did surgery on me for prostate issues and fixed it after I had seen many different doctors who were useless and uncaring and even two surgeries but he fixed the problem and I am great after 3 years! I am just grateful my wife found out about him for me.
