Dianna began her career in public health in 1997 at the MCHD caring for women, infants and children and later went on to become the Nursing Services/Communicable Disease Coordinator. She was responsible for coordination of clinics such as the immunization, well-child, communicable disease, sexually transmitted disease, TB and lead programs.

She helped to facilitate the first Hepatitis C support group in Macon County. 

After Sept. 11, 2001, Dianna had a lead role in emergency preparedness planning, building partnerships and collaborating to ensure public health emergency preparedness. In 2010 Dianna enjoyed working as the school health coordinator for Decatur Public Schools promoting the health and well-being of children.

Her prior experience in public health prepared her for the role of public health administrator for the MCHD, which Dianna accepted in 2014. She leads the MCHD with compassion and understanding, providing steady direction. This year she facilitated a dental forum with local partners to seek solutions for access to dental care for the underserved.
