Growing up, his family owned and operated a small bodega in Hartford, Connecticut in a largely Latino neighborhood. Not only did he learn the importance of hard work, he witnessed firsthand, the stark disparities within the community regarding education, occupation, and healthcare. These experiences sparked his interest to serve his community and to work with the underserved. Dr. Nunez earned his undergraduate and medical degrees from the University of Connecticut. During this time, he helped co-direct a mobile migrant farm clinic that provided free medical care to migrant workers throughout Connecticut. He also spearheaded a Promotora program to empower members of the migrant community to become health educators and advocates within their community.
