5 /5 Vincenzo Cagno: Dr. Roger Kao has been my gastroenterologist since I was just 12 years old. Now at age 20, I can honestly say that he has shown true compassion, and professionalism throughout my experience of being his patient. I have been able to chase my dreams, and live what most would say a normal life is like while battling Ulcerative Colitis. Not only is Dr. Kao great but even down to his team of receptionist’s. Colleen is amazing and always has taken care of me. During a rare occasion if Dr. Kao is on a vacation, Dr. Levenson is quick to step in and deliver the same level of care needed. Overall I have felt apart of the family during my experience with Digestive Care Center in San Carlos CA. The world needs more doctors like Roger Kao.
