Tech Search Party is sponsored by Google, Element Public Relations, Kumon Math and Reading Center, RobotsLAB, Rocket Science Consulting, Umpqua Bank, and UrbanSitter.
Tech Search Party assembles teams to scurry throughout Noe Valley and solve enigmatic clues with their smart phones for a chance to win prizes while also supporting local public schools. All proceeds go directly to local public school PTA groups to help grow their technology infrastructure.
Participating schools this year are: Alvarado Elementary School, James Lick Middle School, and Marshall Elementary School.”
