CHA Tree Logo

Logo Inspiration

Our logo designer's thought process  sums up CHA in a nutshell (pun intended). "The child with open arms upward on a hill expresses the initial letters of our school, friendly, welcoming, openness along with excitement, leadership, ambition, and achievement. The child is the trunk of the tree expressing growth, strength, foundation, and core in a thriving situation. The mechanical gears represent our support system, the spinning wheels represent thinking and imagination, engineering, creativity, and innovation, while the different shapes represent diversity. "

"Some things I love about CHA are dedicated, excited and professional teachers and staff, that everything is perfectly organized, and classrooms are well stocked. Small class sizes of 15 or less, guaranteed before and after school care, great extracurriculars, amazing administration, beautiful facility and grounds, interactive panels in all rooms, tablets for all, big tech lab that each class goes to weekly, healthy/tasty food, multiple snacks during the day, and the ski program! The school provides the ability for teachers to use different curriculums that best suit the child, focuses on the whole child, not just academics and provides art, music, library, Spanish, PE and tech. There are lots of ways for parents to be involved and CHA encourages students to respect each other and treat each other well, as well as provide the framework for good behavior, with tools like Leader In Me and Bucket filling, and then provides lots of positive reinforcement."
