Guadalupe “Rosie” Harrison is a dedicated advocate and community builder who champions inclusivity, equity, and cultural diversity. As the founder and executive director of GROW Initiative GA, Rosie has transformed the organization into a trusted partner for underserved communities, particularly for non-native English speakers and individuals with disabilities in Coastal Georgia. Deeply influenced by her Mexican heritage and her childhood in Las Vegas, Nevada, Rosie is driven by a commitment to creating positive, lasting change.

Rosie’s work focuses on building strong partnerships with local organizations, businesses, and government entities to address critical issues like food security, healthcare access, and educational disparities. Through GROW Initiative GA’s “full circle” framework, she tackles the root causes of community barriers using data-driven strategies and culturally sensitive programming. Her advocacy extends to policy work in education, health, and nutrition, where she promotes equitable, culturally appropriate, and linguistically inclusive resources.

Passionate about fostering inclusivity and collaboration, Rosie is a tireless advocate for the rights and opportunities of diverse communities, working to create pathways to success for those facing educational and economic barriers. In addition to her work at GROW, she is committed to expanding the organization’s reach, securing funding, and advocating for systemic changes that uplift low-wealth, underserved populations.

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.

She recently joined GROW Initiative GA with the goal of furthering their mission by increasing community engagement and outreach to the populations that GROW aims to serve. She is extremely passionate about equal access to healthcare and education, especially for Latin populations, and wants to support her community by increasing GROW’s outreach to Latin communities in coastal Georgia and the metro Savannah area.

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

When she is not working as a medical assistant or volunteering with GROW Initiative Georgia, you can find Callie enjoying a long walk through her neighborhood.
