Daniel Vreeman

Daniel’s work aims to create a global health ecosystem where data is available with open standards that unlock the potential for information systems and applications to improve health decision-making and care. He is a physical therapist, biomedical informatician, and expert in health data standards and interoperability. As an international leader in health data standards, Daniel has led data standards projects supported by federal and other clients, including the National Library of Medicine, Centers for Medicare and Medicaid Services, Office of the National Coordinator for Health Information Technology, Food and Drug Administration, and more. He also led the development of LOINC, an open vocabulary standard for health measurements, observations, and documents, which is now used in more than 175 countries.

“I’m always excited by working with others to create seamless networks of health information systems that help people experience optimal health.”
