Erica Thompson – Ecoliteracy Green Team Instructor
Erica Thompson is our lead instructor for our Earth Ambassadors program with almost 8 years experience in providing sustainable education to students TK through 5th grade. She tries her best to live a more sustainable lifestyle by swapping daily tasks and products for more sustainable/eco-friendly alternatives to reduce the effect we have on the environment. Fun fact: when she was young, she could not decide if she wanted to be an interior designer or a teacher. She ended up studying interior design, but is loving this phase in her life of empowering our younger generation in understanding why the environment is important.
