DISA has added online check in functionality for two Houston area facilities.
While walk-ins are always welcome, you can now save time by reserving your place in line with DISA’s new ‘check in online’ feature.
Pasadena Service Center
5141 Center St. Pasadena, TX 77505
Shell Deer Park – On Site DISA Location*
Only tested / clear contractors for Shell Deer Park can access this location.
How does it work?
Upon notification that your employee is due for a drug test, your designated em
ployee representative (DER) can use the link below and reserve their place in line.
When using the Clockwise Online Check In system, minimal information is required to check in, but we do ask for a phone number (either DER or Donor). Prior to you being at the ‘front of the line,’ Clockwise will text message this number updates and a reminder when it’s time to head over.
By checking in online, chances are you'll be next or almost next in line as soon as you arrive. Please note that during peak hours / peak season your wait time may be longer.
