Maricopa Integrated Health System

What Maricopa Integrated Health System does

Valleywise Health (formerly Maricopa Integrated Health System) is a public, county-operated teaching health system headquartered at 2601 E. Roosevelt Street, Phoenix, Arizona, serving as the primary safety-net provider for Maricopa County. It is owned and governed as a political subdivision of the county through the Maricopa County Special Health Care District, with a board-appointed leadership structure; Dr. Michael D. White, MD, MBA was nominated as President and CEO in 2025.

The system delivers a full continuum of care organized into three service lines: primary care (dental, vision, OB/GYN, pediatrics, pharmacy, telehealth), referral-based specialty services (pain management, cardiology, behavioral health, diabetes care, radiology, surgery), and emergency/trauma care anchored by the Diane & Bruce Halle Arizona Burn Center — established in 1965 and recognized as one of the largest civilian burn units in the nation, serving the entire southwestern United States. The operating footprint includes the Roosevelt Campus–Hospital, the Behavioral Health Annex, Desert Vista, and multiple health centers across the county. The underlying technology stack centers on Epic's MyChart patient portal, which enables self-scheduling, prescription refills, bill payment, and telehealth; the platform is integrated with 16+ language accessibility and financial-assistance workflows.

Revenue is generated through standard healthcare billing across insurance, Medicare, Medicaid, and self-pay streams, supplemented by county-level tax support authorized via Proposition 409 (passed in 2025) and philanthropic contributions. Core clinical staffing is supplied through a longstanding affiliation with District Medical Group (DMG), and the medical-education pipeline is anchored by the Creighton Alliance for undergraduate and graduate medical training. In 2025, the system opened a new hospital and rebranded from Maricopa Integrated Health System to Valleywise Health, marking the most significant capital and identity expansion in its history.
