Healthcare interoperability, FHIR, HL7, and privacy consulting for secure health data exchange.

I help health systems, digital health teams, and standards organizations design secure, standards-based health information exchange, patient access, consent, and AI transparency solutions that work in the real world.

Available for advisory work, strategy engagement, standards review, and implementation support. I partner with health systems, digital health teams, and standards organizations that need practical guidance in FHIR, privacy, security, and health data exchange.
