Ms. Wallace provides enterprisewide strategic and financial leadership for UCLA Health, a $9 billion academic health system encompassing hospitals, clinics, physician enterprises, managed care and joint ventures. She has oversight of revenue cycle, accounting and audit, planning and decision support, supply chain, mergers and acquisitions and contracting. Since joining in 2019, she has strengthened the organization’s fiscal stability, market positioning and operational efficiency. Ms. Wallace pioneered the “Sustaining Excellence Transformation” model to drive margin-enhancing initiatives across labor and operations, pharmacy growth, service mix, supply standardization, length of stay and strategic pricing, generating annual cumulative margin improvements ranging from 1% to 2%. She led financial due diligence for several major acquisitions and affiliations, including a 14-acre medical campus with 260 inpatient beds, a hospital campus dedicated to behavioral health, a pediatric congenital cardiac care affiliation and a strategic alignment with a 105-bed long-term acute care facility. She also supported the system’s readiness and launch of an at-risk Medicare Advantage plan, and her leadership helped give UCLA Health one of the nation’s strongest cash-on-hand positions. Before UCLA Health, Ms. Wallace served as vice president of finance and CFO for San Francisco-based UCSF Health, providing financial direction for the adult hospitals and the physician enterprise. UCLA Health ranks No. 1 in both California and Los Angeles according to U.S. News and World Report and earned a place on its “Best Hospitals Honor Roll” for the 36th consecutive year.
