Internist Profile

As an internal medicine physician I use my knowledge and expertise to diagnose, treat and care for adults with a wide range of health issues.

What makes me unique is that I do this by treating my patients like they are my own family members. I call it my 20-plus rule. If a patient's age is within 20 years of my own, I treat them as if they were my own brother or sister. If they are 20 years or younger, I treat them like they are my own children. If they are 20 years or older, I treat them like they are my own parents. With this approach, I feel I am able to be a more friendly doctor and really approachable.

I want my patients to know that I welcome people of all walks of life and background and I provide a personalized, individualized care. Success in managing any condition happens when the patient and I (along with any of their other providers) are working together as a team. We have shared responsibilities and make shared decisions that will always be in the best interest of the patient.

I knew from a young age that I wanted to be a doctor. I lived in a small village in South Vietnam where there was no medical care available. It scared me to see my mother have an asthma attack. So when I came to the United States at 15, and the opportunities to study and become a doctor were presented, I went for it.

When I am not working, I fish. I have been fishing since I was 5 years old. Anywhere I have lived, I have found a place where I can fish: whether at a park, a lake or on the seashore. Fishing is very beneficial. It calms you down and allows you time to think. I found, even as a student, that sometimes when I fish, I find answers to questions that I could not find sitting at a desk.
