Ms. Sunman oversees all human resources functions for Valleywise Health’s public teaching hospital and safety-net system, supporting more than 4,000 employees across four hospitals and 11 federally qualified health centers. Since joining in 2024, she has led efforts to redesign healthcare work by redefining job descriptions, reassessing workflows, cross-training staff, and implementing new tools to improve efficiency and quality. Facing significant behavioral health workforce shortages, she advanced innovative recruitment strategies that enabled the reopening of all units within a 192-bed behavioral health hospital that had struggled to staff since the pandemic. Ms. Sunman emphasizes integrity, accountability and collaboration while guiding systemwide cultural transformation and change readiness. Valleywise Health has been recognized as an “Outstanding Public Service Organization” by the Congressman Ed Pastor Center for Politics advisory committee and named one of “Arizona’s Most Admired Companies” by AZ Business and AZRE in 2023.
