    My husband and I recently saw Dr. Giannakis and we just had a very great experience at the office. The staff is very friendly, and Dr. Giannakis explained everything very thoroughly. He didn't rush like other doctors usually do, he spent a reasonable amount of time and answered all of our questions and explained all discharge instructions. Very pleased with everyone there.

    I spent over 3 hours at this office and will never go there again. I was not seen by Dr. Giannakis until around 11:25 and my appointment was at 9:15 am. This was the worst experience I have ever had at a doctor's office. I am a doctor myself and believe that this kind of practice shows the public how bad doctor's visits can be.

    Fantastic Doctor that talks with you and actually listens and provides answers in a clear and compassionate manner.

    I've been seeing Dr Giannakis for over 15 years now. The office management at The Woodlands location is inefficient, requiring patients like myself to fill out stacks of forms with information their file management system already has. Additionally, I waited 40 minutes AFTER my scheduled appointment on 9/22/16 (I arrived 10 minutes early so a total of 50 minutes in the reception) before I got up, told the receptionist how long I had waited, and left. There are better docs and options out there.

    He has been my Urologist since mid 1980's. He like going to an old frat brother from college, easy to talk too, gives you straight answers and is always right. I recently had some health issues and spent a month in the hospital. The hospital left a catheter in me the whole month and thought i would have to use one for the rest of my life. Dr. Giannakis assured me he would retrain my bladder and i would be fine, and so I am.
