About

Bio

I am a board-certified internist and nephrologist currently in private practice. My training and experience spans from international medicine in Asia and Europe as well as institutions across the US. I have extensive experience in caring for the underserved, and providing top-notch quality care to many others. I try to be conservative with my approaches to help my patients save money, but also be effective in overall care. I believe every treatment should be catered to the individual person, and every treatment should come with education for the patient in order to help our patient population become more appropriately informed. I look forward to taking care of each and every one of you.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
