He has held a variety of roles and responsibilities in DEMA including Planner of the Georgia Safe Schools Initiative, Emergency Operations Center Manager, Mobile Command Vehicle operator and driver, WebEOC Platform Manager, Digital Engagement and Communications Liaison, and is currently charged with the development of the Drone Program.

Cary has interacted with a wide scope of community, corporate and county partners throughout all phases of emergency management by way of class instruction, community presentations, interpersonal and technical skill partnerships. His background and experience includes roles such as Public Health Communicable Disease & Emergency Preparedness Coordinator and GIS Technician prior to joining Dekalb County. Cary has an educational background that includes a B.A. in Homeland Security and Emergency Management from Savannah State University and a MPA (Master of Public Administration) from Capella University with focus on Public Affairs. Cary has gone on to earn his Georgia Certified Emergency Management designation from the state of Georgia in 2019 and is currently pursuing his International Certificated Emergency Manager Certification.

Breanna Rogers joined the DEMA team in February of 2019. She graduated with her Bachelor’s degree in Interdisciplinary Social Sciences from Florida State University and is currently getting her Master’s degree in Emergency Management. After graduating, she interned with the Florida Division of Emergency Management and Volunteer Florida. Her background in Emergency Management planning consists of work at the Federal, State, and private sector levels. Wanting more engagement with the community she decided to move to the county level where she began working with DEMA.

Her main responsibility consists of reviewing and maintaining county plans. Other responsibilities include managing the CodeRED/IPAWS platform, Public Assistance, Hazard Mitigation Project Assistance, Social Media Preparedness, and Budget & Finance work.  During an active incident, when the Emergency Operations Center (EOC) is activated she is dialed in as the Planning Lead. Drafting Incident Action Plans (IAPs), Situation Reports (SITREPS), and weather briefings becomes her primary role in the Planning Lead position. Breanna’s role is quite impactful as it is her job to maintain DEMA’s operational and preparedness plans so that the agency will be ready to supply resources to county departments during a disaster. While at DEMA she hopes to, “learn as much as I can about the cultural and ethnic differences of each of DeKalb’s unique jurisdictions in order to promote tailored and accessible preparedness plans that incorporate the necessities of each community.”





Scott Tibbetts is the Volunteer Coordinator with DEMA. Ensuring the team at DEMA is augmented with knowledgeable, well-trained, fully equipped volunteers has been Scott’s undertaking since February of 2020. One of Scott’s favorite quotes comes from Benjamin Franklin, “By failing to prepare, you are preparing to fail.” Some goals Scott has set out to achieve within his career are to enhance community education and volunteer programming while developing knowledge and expertise in state and federal mitigation resources. Additionally, he hopes to support citizens in efforts to be proactive, making preparedness a constant state of mind resolving needs during an emergency rather than a reactive state of mind adding to the needs during an emergency. Scott manages the Community Emergency Response Team and the DeKalb County Fire Rescue Reserve volunteer programs.









Yolanda Harkley is the longest tenured county employee within the DEMA team. Captain Harkley began her career with the DeKalb County Fire Department over 23 years ago. She recently expanded her career with the county, transferring to DEMA in 2020. She serves as the Local Emergency Planning Committee (LEPC) Coordinator and the Safety Officer with DEMA. Yolanda brings a treasure trove of knowledge, talent, and experience to DEMA and looks to promote more emergency preparedness within the community and stakeholders through awareness and training. Her future plans are to ensure each citizen is personally aware and prepared for any natural and man-made disaster that may affect our community. She believes that we should always do unto others as you wish them to do unto you.
