Tanvi’s passion for community health began with her work in India — focusing on behavioral health education and service delivery across psychiatric hospitals, clinics, and nonprofits.
While working on a variety of challenges in the health sector (both in the US and India), including the effects of environmental health on community mental and physical health, Tanvi realized the need for broader sector engagement through more awareness, community involvement and policy change across systems. Through Health Care Without Harm, she hopes to address those challenges with a focus on social determinants of health and well-being.
