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.

I would let them know that my waiting time was less than five minutes in the lobby and in the exam room. Dr Oang was especially considerate of my comments and questions.

Dr. Oang has an excellent bedside manner. He is very thorough and his diagnosis are always right on. My family and I have been patients for many years and we trust in his judgement. I could tell Dr. Oang does a lot of research because his explanations and recommendations clarify condition and path forward. He does not hesitate sending his patients to specialist if he feels it is required.
