How It Works
All classes are 100% free and will be conducted either remotely via Zoom or in-person in groups of about 5-10 students. Each class will meet for one 45-60 minute session per week. We emphasize creativity, problem-solving, and collaboration in order to foster a welcoming environment where students can form lasting friendships.
