Direct Experience. Personal Accountability.

Terry Virdell | Principal Consultant & Founder

Expertise Built on Rigor

In clinical data engineering, "close enough" is a liability. When clinical logic fails or privacy protocols are weak, the consequences are measured in patient safety risks and regulatory penalties.

I founded Your Data Health to provide healthcare organizations with senior-level technical auditing that bridges the gap between legal compliance and engineering reality. With over 15 years in healthcare technology, I specialize in the "zero-fail" zones of clinical data.

My approach is rooted in technical authority. I don't just provide a checklist; I dive into the SQL, the Databricks clusters, and the EMR workflows to ensure your data infrastructure is resilient and compliant.

Clinical Logic Governance

Validated critical Sepsis and MEWS predictive models at Providence.

Financial Impact

Delivered $13M in cost avoidance by leading Defect Prevention efforts.

Zero Defect Introductions

Under my review and leadership at Providence and Opala, there were 0 critical or high defects introduced into production over the last 15 years of my career.

E2E Automation Scale

Automated over 50,000 hours of manual testing and validated over 20 million unique healthcare data points across patient and member records.

Secure Your Compliance

HTI-1 regulatory deadlines are approaching. Act with urgency. Technical validation is required. View ONC certification deadlines.

I am currently accepting engagements for Q1 2026 diagnostics.

Fractional Expert Support

For startups and lean teams, a full-time Privacy Engineer is often unnecessary, but technical compliance is non-negotiable. I specialize in working diligently 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.
