Lara Chehab
Co-Founder and Researcher

Lara received her B.S. in neuroscience from UC San Diego, and her Masters in Public Health in Epidemiology and Health Policy from Columbia University. She most recently has experience with the design and implementation of quality improvement projects in primary care practices across New York, Missouri and Minnesota. She has also led research and implementation for school wellness programs at the NYC Department of Health and Mental Hygiene, specifically in underserved communities in Brooklyn. Her commitment to improving mental health disparities in displaced and refugee populations led her to work both in the field with the UN Relief and Works Agency in Lebanon and at headquarters with the World Health Organization in Geneva. When she’s not traveling or thinking about healthcare, Lara is a personal trainer and spends her time designing fitness programs and coaching her clients. Yet one of her greatest accomplishments came as a college student contestant on “The Price is Right,” where she won a lifetime supply of patio and dining room furniture.

She is the founder of Clinica Verde, a healthcare design organization started to create a global prototype of a new model of care for families living in poverty in Nicaragua.
