Sonia Shah, MPH
Vice President, Healthcare Operations
Sonia is the daughter of immigrant parents from India. Although her father was trained as an accountant, he ventured into entrepreneurship after arriving in New York City. As a result, her family lacked insurance coverage, and Sonia spent much of her early childhood receiving care at Community Health Centers in the city. This experience not only introduced her to the high-quality care provided by these centers but also gave her a firsthand look at the challenges of living without health insurance. Watching her parents navigate complex systems and resources with limited English skills and a lack of familiarity with American culture deepened Sonia’s understanding of the barriers that many communities face in accessing essential healthcare. Sonia has always been passionate about connecting people, whether it’s her close-knit circle of friends or broader communities. Working at the Coalition allows her to merge this passion with her skills, finding innovative ways to support member health centers and the communities they serve.
Sonia holds a Bachelor of Science in Biology and a Minor in Psychology and a Master in Public Health with a focus on Hospital and Health Administration.
