Testament:  “After completing my medical training in California's Central Coast, I was thrilled at the opportunity to move to the Midwest and join the wonderful team here in Milwaukee - despite all the warnings about its harsh winters! My interests in medicine have evolved over time, but I've always felt strongly about serving my patients, especially those who have been marginalized, with the same honor and dignity I would expect for me and my family. As a first generation American, I was taught that being a physician is a privilege that should not be taken lightly, and as the first physician in my family, I take the lessons my immigrant parents taught me to heart. I look forward to serving our community and to helping guide our physicians-in-training explore their passions and forge their own paths in medicine.”
