Dr. David Callender
President and CEO, Memorial Hermann Health System
Callender has headed Memorial Hermann since 2019. The system, which includes 17 hospitals, this year launched the Memorial Hermann Institute for the Advancement of Health Equity to focus on innovation and research addressing the social determinants of health. Callender has pointed to the potential for value-based care models to save money and improve outcomes. The organization has put funding toward the issue: In 2023, it invested in Wellvana Health, which provides services to physicians and practices moving from fee-for-service to risk-based contracting models. An ear, nose and throat surgeon, Callender previously spent 12 years as president of UTMB Health and served in executive roles for the UCLA Hospital System and the University of Texas MD Anderson Cancer Center. He is a board member for the Greater Houston Partnership and the University of Houston.
