Dr. Sy's bio

This content was provided by Dr. Sy "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."

Dr Sy and his staff are easy to reach , and will answer questions via the messaging system. He has successfully completed 3 colonoscopies where the previous Dr had to stop. Dr Sy and his staff were able to make an urgent scheduling request happen. I'm so thankful to have them as part of my health team!

Dr. Sy is very professional and organized. My condition was Hep C type 3 which he recommended the new medication that was to be released in 1 month. He followed up and ordered the medication AND jumped through the hoop to get it covered with the insurance. HIGHLY RECOMMENDED! Above and beyond professionalism and personality!
