DIY (“Do-It-Yourself”) Girls’ mission is to increase girls’ interest and success in technology, engineering and making through innovative educational experiences and mentor relationships. We're a supportive community for girls driven by an interest in creating and building with technology.
DIY Girls uses a three-pronged program approach that integrates engagement, capacity building, and continuity to ensure girls’ success. We offer after-school and summer programs that provide hands-on STEAM (Science, Technology, Engineering, Art and Math) experiences for girls. Girls learn technical skills and apply them by creating their own creative projects and inventions.
