Estella Geraghty, MD, MS, MPH, GISP
Chief Medical Officer & Health Solutions Director
Since Dr. Este Geraghty first encountered GIS while working on her master's degree in public health, she quickly understood that geography and health share an important link. In her role as Esri's health and human services industry manager, Dr. Geraghty explores new ways geography can transform community health and modernize social services. Before joining Esri, Dr. Geraghty was a practicing physician in general internal medicine at the UC Davis Health System. She also served as the deputy director of the Center for Health Statistics and Informatics at the California Department of Health, where she led the launch of the state's first open health data portal. The portal exposed actionable information from official state records and relies on maps to help visitors visualize data. For example, Dr. Geraghty and her team used Esri technology to create an interactive map of birth weights in California from 1989 to 2012.
