At GROW Initiative GA, our team is made up of dedicated community advocates who bring both lived experience and professional expertise to everything we do. Each team member is certified as a Community Health Worker through Emory University, a Mental Health First Aider for both youth and adults, and a licensed Community Resiliency Model (CRM) teacher.

We bring a strong foundation in education, disability advocacy, public health, and inclusive service delivery that honors both language and culture. Our team has extensive experience supporting individuals with disabilities and their families, advocating for improved access to education, services, and resources across the lifespan.

We’ve spent years leading community-based education, offering translation and interpretation services, and creating safe, accessible spaces for non-native English speakers and those facing systemic barriers. What truly sets our team apart is our deep passion for serving low-wealth and underserved communities across Georgia. We are committed to this work because these are the communities we call home.
