Why Upper West Side families choose us
Upper West Side families put a premium on learning and on doing things well, and their calendars are full. A birthday party shouldn't become one more project to manage.
At Genius Gems the learning is built in, with real hands-on making, and the managing is ours. We plan the flow, run every activity and handle the details, so you get to be at your child's party instead of running it.
