Meet our familia

We believe we deserve a health care experience where we feel seen and heard. We want a health care team that speaks our language, delivers compassionate care, and aligns with our culture. That’s why we created Zócalo Health.

Our story

Zócalo Health was established following the meeting of our two founders, Erik Cardenas and Mariza Hardin, who had a vision of bringing much needed improvements to primary care in the communities they were born and raised in. What formed is an innovative health care service designed by Latinos, for Latinos. Together, we are building a team that will help remove barriers to health care by offering convenient, transparent, and culturally-aligned care to our members.

The time to fight for culturally relevant, compassionate care for Latinos is now. Because we matter.

—Erik C. & Mariza H.
