We hope you all had a safe and Happy Holidays! Welcome to 2026!! Please see some PAC highlights for January:

New Cardio Equipment: The PAC is in the process of procuring new cardio equipment! State of the art treadmills, ellipticals and extra stair masters will be installed in the cardio room as well as around the track. In addition, the Main PAC will also be getting new spin bikes PLUS a stair master for both the Mark Center and Taylor Building Annexes! The install will take place in Feb/Mar. Notifications will be sent prior as the room will be closed during the transition.

Pool Update: The replacement of the pool liner/plaster is underway. In addition, coordination is being made to replace the tiles around the entire pool deck. We are hoping to have the newly renovated pool ready for operation by the end of January. We apologize for any inconvenience and appreciate your patience as we work on completing this project.

POOL CLOSURE NOTICE

During the Air Handler Replacement Project, the pool was drained for maintenance.
Upon inspection, multiple cracks were found throughout the pool liner. Adding water at this stage could cause further cracking and leaks.

The Pentagon Athletic Center is working with multiple contractors to complete the necessary repairs.
As a result, the pool reopening has been delayed from the original date of Monday, November 10.

We will notify members once a new reopening date is confirmed.

We apologize for the inconvenience and appreciate your patience as we work diligently to complete this project.
