About me
Welcome. I'm honored to have the opportunity to tell you a little about myself as your prospective physician. In my department of behavioral health, I believe it is especially important that you feel comfortable with your personal physician, and I hope this page gives you some insight into my background and my approach to working with members.
Biography
I was raised in Long Beach, California, and Portland, Oregon, where I dove into outdoor sports like backpacking, rock climbing and mountain biking in the beautiful Pacific Northwest. After studying biology in college, I worked in the film industry in Los Angeles doing visual effects during my 20s before feeling called to a career in medicine.
To me, addiction lies at a fascinating crossroads of genetics, public policy, social work, emergency medicine, psychiatry, and neurology (among others), all of which I find fascinating. While still a medical student in Las Vegas, and through incredible encounters with patients in a variety of settings, I made the decision to pursue addiction medicine fellowship training after residency, and I am now grateful to be part of a robust team of physicians, therapists, nurses and social workers in the Kaiser Permanente Addiction Medicine Department here in Southern California.
About my practice
I have often seen firsthand how people who use substances or struggle with addiction can experience stigma in medical spaces. I focus on creating an environment that is open and free of judgment so that you may feel comfortable discussing your personal goals for both substance use and mental health. I see my interactions with members as discussions with shared decision-making, and I hope you feel this as well.
I consider myself both a lifelong student and a teacher and have helped plan conferences for the California Society of Addiction Medicine and regularly give lectures to Kaiser Permanente family medicine residents interested in learning more about addiction.
How I thrive
These days, I enjoy playing guitar, skiing, traveling, doing Orangetheory workouts, seeing live music, and spending time with friends and family.
