It has been an exciting summer, filled with many new opportunities and next steps for CommonWell and our members. Joining us on this journey are three of our newest members – Diameter Health, Particle Health and WellHive, all innovators in the health care IT field.

Please join me in welcoming them to our CommonWell family:

Diameter Health

Diameter Health enables clinical insight through the normalization, cleansing, deduplication and enrichment of clinical data from across the care continuum. The Diameter Health platform empowers organizations that depend on multi-source data streams, such as HIEs, ACOs, health systems and health plans, to realize greater value from their data.

Particle Health

Particle Health enables patients and consumers to authorize and access their medical records within any digital product. Partnering with networks like CommonWell, who are connecting the dots, Particle Health manages a secure and compliant onramp to the largest medical record exchanges in the country via a simple API.


WellHive simplifies the world of health care and distributed care management by empowering seamless healthcare information exchange, insurance verification and scheduling between network and community care providers. With WellHive, patients can access the care they need when and where they want, without creating additional administrative or training burden to providers.
