As a Geriatric Fellowship Assistant Program Director, I’m passionate about engaging learners at every stage—students, residents, and fellows—in shaping their own educational journey. I believe that the best training programs are built collaboratively, with learners actively contributing to their evolution. My specific focus is on developing a resident- and fellow-led “5M Clinic,” where trainees provide direct care and consultation grounded in the core principles of geriatrics. I welcome feedback wholeheartedly and view each rotation as an opportunity to refine and elevate our program to better serve both patients and future clinicians.

I joined the Southern California Permanente Medical Group in 2010. I serve as the Assistant Chief of Service for the Department of Geriatrics, Palliative Care and Continuing Care and the director of the inpatient and clinic based Palliative Medicine service in San Bernardino County.
I was born in Vietnam but grew up in Los Angeles, California. I received my bachelor’s degree in molecular biology from the University of California Berkeley in 2002. I later traveled to St. George’s University in the Caribbean for medical school and completed my Internal Medicine residency in 2009 in Newark, New Jersey from the University of Medicine and Dentistry New Jersey. I later found my way back to Southern California and finished the Hospice and Palliative Medicine Fellowship, Kaiser Permanente Los Angeles in 2010.
