Dr. Oang knew he wanted to pursue medicine growing up in his native Cambodia. “I was sick a lot during grade school, even missing vacations with my family. So, I decided to be a physician to take care of myself,” he says, adding that “Internal medicine offers a broad base of knowledge, which enables me to take care of patients with all different medical problems.”

Dr. Oang survived Cambodia’s brutal dictator Pol Pot and the Khmer Rouge regime, responsible for killing more than a million people in the 1970s. Today he likes to vacation with his family.

that I was really disappointed in the way the system overloads dr. Oang. People need to have their health problems resolved and that is through communication. I would recommend Sy Oang wholeheartedly but not the PIH system. Now I don't trust the system.

Dr Oang is always pleasant, thourough, and very competent. Dr Oang is a good diagnostician and I always get well sooner than later. Dr Oang will refer you to a specialist when your medical issues indicate it is necessary. He always makes sure you understand what your medical issues are and why he is prescribing the meds he is. He takes time to explain your lab results to you and will always answer your questions completely. My health has continued to get better and better this past year I owe this to Dr Oang's constant encouragement to be in the best health I can be and what steps to take to make it happen. Happy, satisfied patient !! Thank you PIH for hiring the Best of the Best!

PIH has improved since I left this IPA 10 years ago. They are more efficient and proactive with their approach with health care. The check in was easy, parking good, very clean and modern building Dr. Oang is kind, knowledgeable and listens. He is easy to connect with and is willing to spend time (within reason of course) with a new patient (me) to establish a patient-doctor relationship that is so important. I'm very pleased so far! I have already shared my opinion with my husband, who is considering a change for his PCP and IPA.
