Administrative Team
CHHS has a team whose members have different job titles and job responsibilities but are bound together by a common denominator; the welfare of students. Team members actively work to create a positive school culture in which all people, students and adults, are viewed as valuable, worthy, and possessing a dignity to be respected.
