Kiasha Huling, MSW is a graduate of Temple University’s College of Liberal Arts with a degree in Psychology and the School of Social Policy and Practice at the University of Pennsylvania where she earned a Masters in Social Work. Kiasha’s career began in direct service social work and research. Later she created and directed Social Work and Outreach programs for Sayre Health Center, a school based federally qualified health center in West Philadelphia. Through working in communities for public health campaigns and resource education Kiasha discovered the intersection of environment and health. A frequent theme that emerged was that a greener and safer environment encouraged residents to engage in proactively managing their health and wellness through outdoor recreation and socialization.

Kiasha would go on to lead UC Green, Philadelphia's oldest and largest community greening nonprofit. Through collaboration with academic, civic and business sectors, UC Green has planted and maintained over 5000 trees in West and Southwest Philadelphia. She introduced models of programming and engagement that amplified environmental equity and social cohesion, including the UC Green Equity Fund that addresses environmental barriers in planting residential street trees like old tree removal and sidewalk repair so that neighbors who cannot afford to fix problems that prevent them from having a tree are not excluded from tree planting.

Today Kiasha is an organizer with Clean Air Council, building capacity, community and coalition around accessible trails and the Cobbs Creek and environmental concerns. She serves as a consultant for nonprofit development and relationship building. Kiasha served on the boards of Food Moxie and UC Green. She continues to support neighbors in realizing a community held vision for more equitable, abundant, vibrant vision of a greener, healthier, safer Philadelphia.
