Dr. Grenardo has held numerous high-impact roles throughout his career, including Chief Medical Officer and Chief Diversity and Inclusion Officer at Centura Health/CommonSpirit Health, Medical Director of its Clinically Integrated Network, and Dean of Admissions at the University of Colorado School of Medicine. His leadership has touched every level of the healthcare system, from clinical integration to medical education and health equity.
A Stanford University graduate with a degree in Human Biology, Dr. Grenardo later earned dual master’s degrees in Business Administration and Health Administration before completing his MD at the University of Colorado School of Medicine.
