Direct Experience. Personal Accountability.
Terry Virdell | Principal Consultant & Founder
How engagements start: TAP Intake is the written scope form (nothing stored on this site). We usually follow up by email or a short call to confirm fit. When you are ready to commit, TAP Assessment is where you pay and schedule—both are intentional steps so pricing and calendar stay in one place.
Expertise Built on Rigor
For over 25 years, we have worked at the intersection of complex clinical data engineering, rigorous data privacy, and organizational strategy. Terry Virdell leads the firm as Principal Healthcare Architect and technical advisor—maintaining a track record of zero critical defects introduced into production over the last fifteen years.
Your Data Health partners with mid-market health systems and Series A–C digital health startups to navigate HTI-1, USCDI v3/v4, and MHMDA risk. We deliver technical validation, architecture checkpoints, and fixed-fee compliance coaching so lean teams meet interoperability mandates ahead of critical deadlines.
We believe rapid AI innovation must not come at the expense of patient privacy. Our practice applies Privacy by Design and Zero Trust patterns in every pipeline we steward (with team members pursuing CIPT certification). We rely on autonomous LLM agents, Python, and synthetic data workflows to rigorously validate models—without exposing protected health information.
Beyond architecture, leadership runs deep. From directing thirty-plus-person engineering departments at Providence St. Joseph Health to scaling startups from the ground up, we scale this consultancy with productized regulatory fluency—including participation in the April 2026 Founder Institute cohort—to coach healthcare teams effectively.

- Azure, AWS, & GCP
- How we build: Python & SQL on GCP (Healthcare API, BigQuery); LLM-assisted validation & synthetic test data
- EMR/EHR workflow validation
- MHMDA & HIPAA compliance
- Clinical data de-identification
- ISTQB quality standards
- ETL & data pipeline security
- Conformance & API testing (Inferno, Touchstone, Postman)
- QA automation & LLM-assisted test design (GenAI / RAG)
Secure Your Compliance
HTI-1 regulatory deadlines are approaching. Act with urgency. Technical validation is required. View ONC certification deadlines.
Start with intake to describe systems and constraints; move to assessment when you want to pay (Stripe) and hold time (Google Calendar). Same pattern as our FAQ.
Fractional Expert Support
For startups and lean teams, a full-time Privacy Engineer is often unnecessary, but technical compliance is non-negotiable. We specialize in engaging within small-team constraints and tight runways.
The Milestone Model:
- ✔ Architecture Checkpoints: Validation before you scale.
- ✔ Release Audits: Pre-deployment privacy & logic verification.
- ✔ Diligence Readiness: Ensuring your data posture stands up to investor scrutiny.
Leverage senior-level clinical data engineering only when you need it - keeping your burn rate low and your integrity high.
Need scope before budget? Use intake first. Already aligned and ready to book? Either path works—we separate the form from payment so your details stay out of checkout flows.
