A Little More About Me

In addition to spending time outdoors, I’m also very passionate about education. I spent 4 years volunteering with TEALSK12 where I taught computer science to Bay Area high schoolers. I had the opportunity to be exposed to computer science through my high school and it changed me forever. I aimed to have that same effect on the students that I taught.
