About us
Thesaurus Health is a healthcare data solutions company specializing in OMOP CDM, real-world evidence, and semantic interoperability. We’ve worked across academic, commercial, and multi-institutional research environments — delivering data solutions that enable meaningful research at scale.
Our mission
is to make complex healthcare data usable, standardized, and ready for science. We believe that real-world evidence starts with structured, interoperable, and semantically rich data — and we’re here to help you build exactly that.
We operate remotely, work globally, and collaborate closely with each client to deliver high-quality outcomes with speed, flexibility, and precision.
We’re proud to be a company where top-tier professionals can do meaningful work — without compromising on well-being, ethics, or purpose.
This philosophy shapes everything we do — and the way we work with every client.

Company and Team
Thesaurus was formed at the beginning of 2025. However, the Team consists of seasoned experts, who have been working with OMOP CDM and standardized healthcare data since even before the OHDSI initiative was formally established. Our experts helped shape early versions of the OMOP Common Data Model and vocabularies — and continue to contribute to its evolution through open-source projects and real-world implementations.
We have a proven track record as trusted OMOP CDM and terminology experts, with hands-on experience in large-scale data conversions, semantic infrastructure, and open collaboration across the OHDSI community and many others.
