Sunset Spark unofficially started in the Summer of 2008 when Yadira and Gaelen taught 3rd and 4th graders soldering and robotics at P.S. 24 in Brooklyn. In 2013, they began pursuing Sunset Spark's mission full-time by partnering with neighborhood schools to provide in-class creative technology instruction.
