A Note from our Executive Director


I am honored and grateful to welcome you to the Colorado High School Charter’s community.  Honored because you have unique gifts and talents that you bring to our community, and grateful because you have chosen CHSC as your educational path. 


We invite you to join us in stretching ourselves and learning from each other while becoming better educators, students, and human beings.  The responsibility we share is an awesome one because we are working to change our community, city and world by educating young people.  I believe education is key to freedom both personal and economic, the education we are providing is preparing students for their next steps in life – a career, trade school or college. This task can be difficult yet from my experience I know we will all be surprised and inspired by each other. 


Thank you for the work you will do this year, thank you for the experiences and wisdom you bring to CHSC and thank you for your commitment to education!
