I was born in Stockton, CA, but have spent the majority of my life in Davis, CA, where I did all my schooling from elementary school through medical school. In college I double majored in Physiology and French, but I enjoyed my French studies far more because they gave me exposure to theater, poetry, literature, linguistics, and music. I even taught French, but despite all of this, I have yet to visit France! In medical school, I co-directed a free clinic in Sacramento where I had the chance to not only take care of the local underserved populations, but also to mentor a group of undergraduate students. Teaching and mentoring have always been passions of mine, and I very much enjoy guiding students in their academic and professional careers. I’m thrilled to be at O’Connor because the residents, faculty, and staff are so kind and supportive, and they foster a very positive learning and work environment. I also speak Farsi and enjoy having Farsi speaking patients.  

In my spare time I enjoy painting with acrylics on canvas, taking trips to Monterey and San Francisco to visit the beaches and the city, and spending time with my husband and family.

Fun Fact: I love birds and have a cockatiel and a conure.

I’ve been lovingly shaped by the many places I’ve lived: China, Virginia, Canada, and California. Not to mention all of the fun cities to which I’ve traveled! Volunteering and research in underserved communities in China and the U.S. helped show me that primary care was a basic need across the globe, and my desire to learn the common language to fulfill that need made family medicine the right choice for me. I am excited about O’Connor’s commitment to both the underserved (large MediCal population, FQHC) and medical education (OSLER program), and my husband is excited to finally be in Silicon Valley where people actually speak his language (Java, C++, etc.). The amazing people here foster a nurturing environment that feels at once stimulating and family-like. 

Outside of the hospital, I love hanging out with fun people, wining & dining, dessert, music, and pre-contemplating what it takes to become an American Ninja Warrior.

Fun Fact: I can name 40 different grape varietals used to make wine.

Originally hailing from NorCal, I completed my medical degree in Hershey, PA (where they make the chocolate) at Penn State College of Medicine. I am so happy that I no longer have to worry about snow tires and shoveling out my car to get to work! Before medical school, I had a few careers. I worked for the Los Angeles County Board of Supervisors doing public policy work. I taught K-2nd grade at a before-and-after school program, and also taught high school English for a while. I also attended law school for a year. After all that soul searching, I decided on medicine, and I’ve never looked back!

I chose O’Connor for a multitude of reasons. Throughout the interview season, it was very evident that the faculty and leadership are very approachable, genuine, and honest. Additionally, I wanted to train at a program that was community-hospital based, but also offers the academic connection to and support offered by a larger university. With my education background, our OSLER program was definitely a draw. Now that I am here, I could not be happier with my choice! Our attendings are awesome, and the O’Connor residency and hospital staff are extremely welcoming. My fellow residents come from a multitude of backgrounds, and I learn something new from them everyday.

Fun Fact: I love doing fun hip-hop aerobic classes, oil painting, DIY projects, and hanging out with my husband, our puppy, and our baby boy.

Areas of Interest:  Adolescent Health, Medical Student Education, Underserved Populations, Women's Health

Before residency, I grew up in Indiana and then went to Duke, where I was a biology major and English minor. I then spent three years teaching 9th grade biology in Chicago with Teach for America. My experiences on the west side of Chicago drove me to work toward healthcare and educational equality. During medical school, I worked to encourage medical students to reach out to community high schools and educate adolescents about their health.

I picked O’Connor because of the motivated residents I met, the mission of the OSLER program, and everyone’s dedication to the underserved. I feel so fortunate that I was right and have found that the residents and faculty are also collaborative, supportive, and enjoy spending free time together! I’m so pleased my class has found time to have weekly activities together.

Fun Fact: In my free time I enjoy hiking the local trails with my husband, playing board games, watching Duke basketball and the Indianapolis Colts, trying to distinguish my palate at wineries, writing raps, and planning my next vacation.

I was born and raised in Myanmar and immigrated to the U.S. in 1998. I received a B.S. degree in Biochemistry from San Francisco State University and went to UCSF for medical school. During college and a couple of years prior to medical school, I was involved in several different fields. I tutored at the Learning Assistance Center in SFSU and worked in a research lab while volunteering at an emergency department and a grassroots student-run free clinic. It was the latter which inspired me to pursue medicine and reinforced my passion to provide care for underserved communities. I am excited to continue my passion at O’Connor while caring for many patients from diverse cultures and backgrounds. O’Connor has been a truly amazing place for me. I love that it has a great nurturing, supportive, and friendly environment created by approachable faculty, residents, and staff. It makes all my hard work during my residency worthwhile.

Fun Fact: Aside from my love for O’Connor, I also enjoy traveling, sightseeing, eating great food, and spending time with my friends/family.

"From West Philadelphia, born and raised, on the playground was where I spent most of my days…."

Well, not born, but I was raised in Philadelphia for the better part of my life and decided that I was tired of the humidity and needed the sunny and dry warmth of California. I went to the University of Pennsylvania for college and then Jefferson Medical College for medical school. I grew up wanting to practice medicine; then in college I decided to be a writer until I realized that I am terrible at writing and decided that my talents and interests were better suited to both the sciences and people. I chose O’Connor because of the friendly residents and the dedicated and approachable faculty.

Fun Fact: In my free time I like to play basketball and golf, but now that I’m in NorCal, I have decided to pick up hiking and surfing to complete the California experience.

I am originally from Zimbabwe and came to the U.S. for college.  I have lived in both coasts but was lured into staying in the West Coast for longer!  However, the African sunset always beckons. 

Fun Fact: Goals for the remainder of residency are to run 12 (half) marathons in 12 months and to learn Polish.

I grew up in San Jose, so I’m thankful and happy to be back serving my community (although I never strayed too far from home during college or medical school!). Prior to starting college, I went on a humanitarian trip to SE Asia, where I built houses, dug wells and taught English in the poor countrysides. This trip ignited a passion for service, so I founded a non-profit organization called Project Red Balloon to change children’s lives through music. During medical school, I was granted an Albert Schweitzer Fellowship and through this opportunity, I worked with the Asian-American Donor Program (AADP) to increase minority representation in the national bone marrow registry by targeting high school seniors to consider becoming donors when they turned 18 years old. I love O’Connor because of the down-to-earth faculty, supportive residents, and the mission to care for the underserved.

Fun Fact: I’ve hugged Justin Bieber (twice), and I love french fries.
