EngineerGirl (2016 - present)
Contributor to the EngineerGirl websitecall_made which highlights women in engineering and answers questions girls and young women have regarding careers in engineering.

Robotics outreach (2015 - 2016)
As part of the NASA robotic mining competition our team participated in community events designed to expose kids (aged 5 – 16 years old depending on the event) to science and technology. I acted as the team outreach coordinator organizing and participating in all events. Example eventcall_made.

Expanding Your Horizons group leader (2013, 2014)
An annual event at Montana State University (now called MSU STEAM Day)call_made to introduce middle school aged girls (11 – 14) to science, technology, engineering and math (STEM). As a group leader, I guided my group of girls through various hands-on STEM activities around campus, answered their questions and acted as a mentor.

Girl Scouts Badge Day leader (2013)
I helped Girl Scouts earn their engineering badge by guiding them through engineering projects.

Boys and Girls Club mentor (2012 - 2013)
These clubscall_made provide a safe place for youth during non-school hours particularly for kids with no place to go after school. Along with other NCAA athletes, I spent time with kids at the club on a recurring basis to build relationships and be a role model.
