About Me

Dr. Sy was glad to return home to Orange County for his internship and residency program at UCI Medical Center. During his residency, he was a Chief Resident in internal medicine overseeing newer residents' training. Additionally, Dr. Sy also completed a three year post graduate fellowship in Gastroenterology at Kaiser Hospital in Los Angeles.

Originally, Dr. Sy thought he would follow his "family of scientists" into a laboratory research field, but after working in a lab for a while, he found that clinical work involving patient contact better suited him.

I chose Gastroenterology because I enjoy the opportunity to perform procedures and still get to know my patients over a period of time. I know it sounds cliche, but I really do enjoy caring for patients. I like to see people get better!

Dr. Sy is board certified in gastroenterology.

Dr. Sy has volunteered his time and skills on numerous occasions including New Orleans Hurricane Katrina post hurricane Relief. In addition to volunteering, he likes to play and/or watch basketball and tennis, and spend time with family, friends, and his dog, Milo.

As a specialist, Dr. Sy may not be selected as a primary care physician. Accepts patients age 18 and over.
