When COVID-19 exposed the limits of Arizona's public health data infrastructure, the Arizona Department of Health Services didn’t patch the cracks — they rebuilt from the foundation up.

In this session, ADHS and Slalom shared the story of a multi-year data modernization journey that began with a bold vision, navigated the realities of public sector headwinds, and ultimately landed on Snowflake as the cornerstone of a statewide enterprise data platform.

From ingesting core vital statistics to connecting infectious disease surveillance, county partners, and the public through trusted, real-time data, this is a story about what becomes possible when a bold vision is carried through to bold action.

What was covered:

• How a pandemic-era crisis became the catalyst for a statewide data modernization effort and the leadership resolve it took to make it real
• How ADHS evaluated and selected a modern data stack, and why Snowflake emerged as the enterprise data lakehouse of choice for a mission-critical public health environment
• How the platform expanded from an initial Vital Statistics proof of concept to span multiple complex data domains, and what Snowflake-to-Snowflake sharing has unlocked for county and tribal partners across Arizona
• How the data lakehouse became the backbone for a complete rebuild of Arizona's statewide infectious disease surveillance system and how that integration will power a faster response to future public health events
• Where ADHS is headed next, and the emerging opportunity to apply AI and machine learning to public health data at a scale never before possible
