About Me

Why I chose to pursue a career in healthcare:

My parents were in the medical field, so I chose to follow in their footsteps. I felt it was an honorable career.


What I want my patients to know about me:

I was born in South Korea and moved to New England at the age of 12. I spent four years in China helping local indigent patients. With my previous anesthesia training, I have knowledge of pain procedures and perform some of them in the office.


What I do when I'm not seeing patients:

I enjoy taking landscape and nature photos and enjoy listening classical and light jazz music. I used to ride 400CC scooter.
