Lauren Steingold spearheaded the launch of Uber Health, Uber’s HIPAA-compliant service that allows hospitals, doctor’s offices and other health facilities to request rides on behalf of their patients.

The company views the program as an overdue response to a costly problem. Studies show missed appointments cost the healthcare system $150 billion annually and that 3.6 million patients miss or postpone appointments because of transportation-related issues. Uber Health claims its service has already contributed to a decrease in no-show rates and improved cancellation rates.

Steingold is an Uber mainstay. Prior to accepting her current health-related role, Steingold helped launch Uber in Miami, Boston and Rhode Island. She led the company’s on-demand flu prevention campaign, an initiative that won an innovation award at the National Influenza Immunization Summit in 2015.

Before joining Uber in 2013, Lauren held roles at Allen & Gerritsen, an advertising agency in Boston, and the Institute for Healthcare Improvement in Cambridge, Mass.
