World Beard Day: Rehagen Edition

Some have spent years growing them. Some probably just forgot to shave. Either way, it’s time to put all that facial hair to good use.

We’re letting YOU decide who has the best beard, mustache, goatee… or whatever you want to call what’s happening on their face.

LIKE the photo of the employee you think deserves the win!

The stakes are high: a Pizza Haus gift card AND bragging rights until we get tired of hearing about it.

Choose wisely. May the best facial hair win!
