Meet Our Team

GROW Initiative Georgia’s team members represent a group of dedicated workers and volunteer who are extremely dedicated to GROW’s causes and mission.

Executive Director

Rosie Harrison is a dedicated advocate and community builder who champions equity, inclusivity and access. As the Executive Director of GROW Initiative GA, Rosie transformed the organization into a trusted partner in Coastal Georgia, particularly in education, health, and community development. Rosie has earned degrees in Special Education, Early Childhood Education, and several certifications including Community Health Worker, Mental Health First Aid for youth and adults, and is a certified instructor for Community Resiliency Model. Deeply influenced by the experiences of the families she served for the past 14 years and her own difficulties in accessing services for her family, Rosie is driven by a commitment to creating positive, lasting change.

Rosie’s work focuses on building strong partnerships with organizations, businesses, and government entities at a local, state, and national level to address critical issues like healthcare access, educational disparities, and disaster prevention. Through GROW Initiative GA’s “full circle” framework, she tackles the root causes of community barriers using data-driven strategies and community-centered solutions. Her advocacy extends into policy work in education, health, and community development and ensuring communities have access to essential services and resources. In addition to her work at GROW, Rosie is committed to expanding the organization’s reach, securing funding, and advocating for systemic changes that uplift communities that are low-wealth and have been historically marginalized.

Community Outreach Coordinator

Callie Cristina Mauersberg is a Colombian-American dual citizen born in metro-Atlanta. She holds a Bachelor’s degree in Biology with a minor in Spanish Language and Literature from the University of North Georgia and a Master’s degree in Biology from Georgia Southern University.

Callie is extremely proud to serve coastal Georgia as GROW’s Community Outreach Coordinator. GROW’s missions supporting equitable access to healthcare and education are especially important to her, as she is dedicated to community health and improving quality of life for all communities, especially those which are marginalized. She currently serves GROW at their health education initiatives and in community outreach roles.

Since moving to Savannah in 2024, she has fallen in love with Chatham County and its surrounding areas. To give back to coastal Georgia, she sought to support communities which were not equitably represented in healthcare and health education. To this end, she became involved with GROW after graduating from Georgia Southern University with her Master’s degree in Biology, and has since only grown in her passion for accessible health and education initiatives.
