Dr. Diana Greene is the former superintendent of Duval County Public Schools in Jacksonville, Florida. Duval County is the nation’s 20th-largest district, serving approximately 130,000 students in 200 schools. In 2021, The Florida Association of District School Superintendents selected Greene as Florida Superintendent of the Year. She was the second African-American woman to receive the honor.

During Greene’s tenure, Duval County increased its schools rated “A, B, or C” to 93 percent under Florida’s rigorous school grade accountability system. The district also achieved historically high graduation rates.

Prior to Duval County, Greene was superintendent of the School District of Manatee County, also in Florida, where she implemented a leadership plan that centered around what she called the Five Cs: Calmness, Consistency, Civility, Confidence, and Community. Under her leadership, Manatee County improved to receive a B grade from the state, and graduation rates rose 5.6 percent—nearly 3 points higher than the statewide graduation rate.

During her more than three decades as an educator, Greene worked as a teacher, assistant principal, and principal. She also served in roles related to curriculum development, staff development, and senior executive leadership. Greene obtained her bachelor’s from University of North Florida; her master’s from Nova Southeastern University; and her Ph.D. in K-12 education, curriculum, and instruction from Capella University.
