The Pima County Health Department is reshaping public health through a Human-Centered Design (HCD) approach that actively involves the community in program creation. Supported by PHIG funding, the department introduced HCD training courses for staff and partnered with Greater Good Studio to guide three teams in addressing key issues like tobacco prevention, mental health, and racial health. These teams, composed of staff and community members, are co-designing program improvements to reflect real needs and challenges. By early 2025, these efforts will result in community-led program changes and a sustainable HCD toolkit to guide future initiatives.
