About Us

Diameter Health empowers organizations to deliver better healthcare through better data.

Founded in 2013 by John D’Amore and Eric Rosow, healthcare experts who recognized that creating a better way to unify, organize and enrich this sea of clinical data would improve healthcare outcomes and reduce costs.

To build the technology to meet this challenge, we needed the best people. So we built a cross-functional team of innovators with deep domain expertise in healthcare and informatics to design, build, deploy and support what is today the standard for optimizing clinical data in real time and at scale: our FHIR-enabled Fusion technology.

The Diameter Health team shares a vision of transforming healthcare by making data universally accessible, organized and actionable — and the drive to make that vision a reality.
