Office of Border Public Health

Our mission is to improve the health and well-being of the people living within the U.S.-Mexico border region by collaborating with partners and leveraging resources within and outside of Texas. OBPH builds relationships within communities to foster a safe and healthy environment and living practices. We monitor and share data on public health issues and their impact, support binational public health coalitions, conduct community-based initiatives, and support Community Health Workers. 

We operate under the assumption that public health problems cannot be contained within international boundaries and that the U.S.-Mexico border region is one epidemiological zone. We work together to keep Texas healthy by keeping our border healthy. 

About the Mandate
