I absolutely love Robofun / Vision Education and Media. They run camps and after school programs for ages 6-10 in Lego robotics, video game programming and animation/claymation. The subject matter is fascinating and great for kids who are into such things, but this place really excels because of its staff. I’ve talked to a lot of camp personnel in my day, and Robofun personnel are the most engaged (I like everyone there a great deal, but Maria and Isaac stand out to me the most for their caring and going above and beyond for the kids). The people there LOVE what they are doing and their passion and enthusiasm really rubs off on the kids. I cannot say enough good things about the place.
NYC day camp?
