Head shot of Aaron Michael BriggsAaron Briggs, MD

Aaron Briggs was born and raised in San Diego and attended Dartmouth College for undergraduate study. He then attended the Geisel School of Medicine at Dartmouth where he clarified his passion for helping children and addressing health disparities both local/community and national. Aaron’s eyes were first opened to the painful, tangible effects of inequality by seeing the violent and resource-deprived communities that his family lived in. Aaron worked to address the gun violence epidemic/crisis by partnering closely with grassroots community-based organizations which hailed from and represented the communities most affected and helped initiate an outpatient gun lock program. Noticing high rates of food insecurity among families at his continuity clinic, Aaron forged a partnership and developed a fresh food referral service between Children's Hospital of Philadelphia primary care clinics and a Philadelphia-based non-governmental organization (Farm to Families). Aaron came to UC San Diego to pursue his passion for addressing the local and national disparities in health contributing to excess, preventable morbidity, and mortality.
