I am the health officer of the City & County of San Francisco, and director of the Population Health Division (PHD) at the San Francisco Department of Public Health. Striving to embody and promote the universal values of humility, compassion, equity and dignity, I work to convene, connect, and catalyze communities and institutions to transform narratives, policies, and systems toward a sustainable culture of equity, healing and health for all people and our planet. As health officer, I exercise leadership and legal authority to protect and promote equity and health. As PHD director, I direct public health services. I teach population health data science (with R) at the UC Berkeley School of Public Health and I maintain a public health blog (https://taragonmd.github.io) with a focus on population health equity, leadership, lean, and data science.
