Dr. Keyloun was a pleasant and proficient surgeon who answered all of my questions factually prior to and after my surgery. I had very little trauma after the surgery with little pain and discomfort . Analgesics were rarely needed and healing is occurring quickly.

I came to know Dr. Keyloun when admitted to Sibley through the ER. He did an excellent job monitoring me and helping me address a difficult situation without surgery. My follow-up appointment was equally outstanding. He explained my situation using the CT scans to support his recommendations regarding next steps. I will probably be doing additional surgery with Dr, Keyloun based on his knowledge and strong support while in the hospital.
