Krista Chiaravalle

Middle School Teacher
She, Her, Hers

“Education is not the filling of a pail, but the lighting of a fire” - WB Yeats

Krista is our new lead middle school teacher. With over 15 years of experience in education, she wholeheartedly believes that children are hardwired to learn and need to be given a safe space to explore their passions and interests. Like our students, Krista was also educated in a nontraditional setting at the Jefferson County Open School in Lakewood where she attended kindergarten to 12th grade. It was at the Open School where she discovered a true passion for learning and the importance of community.

She began her teaching journey in the San Luis Valley where she helped disadvantaged students in the Upward Bound Program. From there, she moved to the Front Range where she taught biology at Niwot High School. Most recently, she was the STEM coordinator and instructional coach at Sunset Middle School teaching students coding, robotics, and engineering skills.

Krista lives in Lyons with her husband and two teenage daughters. She loves being outdoors, so on any given day you may find her rock climbing, boating, fishing, hiking, or skiing with her family. She also adores traveling and has plans to go to Uganda next summer to help a secondary school set up a STEM lab.

Eitan earned his undergraduate degree in liberal arts at St. John’s College, the nation’s third-oldest school. He lived in Israel, where he had the opportunity to solidify his understanding of Hebrew. Eitan pursued his interest in teaching by working first at The Santa Fe Children’s Museum and then at a Boys and Girls Club in Portland, Oregon.

Since then, Eitan has returned to his hometown of Boulder and spent five years teaching in the public school system including three years in the Boulder Valley School District.

Lindsey Gillette

Social Studies Teacher
She, Her, Hers

At 5 years old, Lindsey set up her stuffed animals (and little brother) so she could play teacher. Teaching has always been her calling. She earned her Bachelors of Arts in History and Education from Colorado State University. Shortly after graduating from CSU, she embarked on a new adventure and moved to South Korea where she spent a year teaching English and experiencing life abroad. Lindsey returned home to teach for ten years in Denver Public Schools. Her experience teaching has included Math, Student Council, History and Civics, AP Psychology, and Economics of Social Issues.

In August of 2020 Lindsey began teaching at Sept School and despite all the challenges of the 2020/2021 school year, she feels September School is exactly where she belongs.

Lindsey's passions outside of teaching are giving her two dogs and two cats the absolute best life they could imagine and working and fighting for Social Justice, Animal Justice, and Environmental Justice.

Jeff backs up his Bachelor of Arts in Psychology/Anthropology with a black belt and 25 years teaching martial arts. Our performing arts instructor since 1993, Jeff also teaches basketball and weightlifting along with classes like Chi Kung, Art of the Sword and Human Issues. Jeff’s wilderness and leadership trips often prove to be life changing for our students, and his daily all-school community class is part of the fabric of our school program. “I have the freedom to be who I really am here,” Jeff says, “and I love that I have the opportunity to form real, authentic relationships with my students.”

September School offers the chance to help students establish and solidify their values at a time when they’re questioning the reality of everything in their lives.” —Jeff Hamilton
