Dialing 911 will call Emergency Services

 In the case of an emergency, call 911 

Stay on the line with the emergency operator until they authorize you to end the call. 

After the emergency call, call the Front Office at extension 610 to engage Overlake's first responders.

If you mistakenly call 911, simply stay on the line and let the operator know it was a mistake. Also, call extension 610 to let them know it was a false alarm.

on-campus - call 600 or press the Messages button on the desk telephone.
