Charlie joined the KAS team in 2020 as a Middle School Science and Design teacher. He earned a Bachelor of Science in Environmental Science (2010) from Southern Oregon University, where he was actively involved in campus sustainability projects. He is a certified teacher through the State of Florida and is endorsed in Math (grades 5-9) and Science (grades 5-9). Before teaching, he worked in a variety of schools and businesses reducing their environmental impact by implementing recycling programs, diverting waste streams, reducing paper consumption, and providing sustainable energy sources. Eventually, he found that he could make the greatest impact by teaching the next generation the importance of conservation, environmental ethics, ecological awareness, and sustainable living. Mr. Chao has high expectations for students to demonstrate critical thinking and independent decision making.
