• Highlands needs more dads to fill the role in All Pro Dads. Please visit the office for more information. All Pro Dads is an exciting new alliance of dads and dad-like positive influences of our great students throughout the Cedar Hill ISD.  CHISD All Pro Dads is an opportunity for male role models to connect with other men who are committed to the success of their child or children.  These men not only positively influence their sons or daughters but their presence directly impacts other students as well.
