Our Coordinators

Sienna Anderson

Hi! I’m Sienna, one of the GIS coordinators. Simon, Sohum, and I work together to oversee Summit logistics and provide support to our four amazing committees. My favorite part of the Summit is learning to see the world from so many different perspectives, and I love watching each view add a little bit of magic to the kaleidoscope that is GIS.

Sohum Kothari

Hello! I am Sohum and I am one of the co-coordinators for GIS 2025. I love GIS because of how it allows today’s youth to raise awareness to a variety of potent issues that we face in the modern day. Our world is depending on this generation to help make it a cleaner, healthier, and safer place to live, and GIS is a place where people with backgrounds and skillsets can all come together and use their shared passions towards helping mankind to contribute and give back to our planet.
