Sharon
Langshur

Operating Partner

My entire working career has been dedicated to healthcare, initially as a physician and later as an entrepreneur. Further life experiences, including parenting children with complex medical needs and overseeing health insurance benefits for employees, have rounded out my experience. Throughout, I’ve witnessed both the inherent human and societal need for quality healthcare and the enormous headwinds created by divergent financial and social incentives.

Working together to address these complex issues was our formative commitment when Abundant Venture Partners was founded in 2011. Having spent several years as Chief Operating Officer then transitioning to an Operating Partner role to engage more deeply in creation of new ventures, I’ve been fortunate to have a front row seat to healthcare innovation.

Working with the Abundant team, sharing a mission-based orientation, and benefiting from the team’s subject matter expertise has been stimulating, challenging, and incredibly rewarding.

Outside of work, I love spending time with my family, am a passionate reader, an occasional Peloton rider, and enjoy cocktail hours (preferably not virtually!) with friends.
