Sara Eshelman focuses on real problems in health and family life, with recurring interest in genomics, pediatrics, and baby gut health, and she sees parents as early adopters whose behavior can hint at where healthcare is headed, having explored genomics and data privacy years before it became a popular topic. She uses writing as a regular part of how she thinks through investments, often highlighting founders who work in overlooked areas and measure success on their own terms, and her perspective is shaped by her own experience as a parent navigating family health decisions.
