Our old Director of Operations (he just switched jobs) is a Tau Kappa Epsilon.
One of the recruiters used to be an Alpha Tau Omega (he deactivated after his parents stop paying for it).
One of the Project Cooridnators is a Zeta Phi Beta.
Going through the parking garage I've only noticed one other greek person and she's a Sigma Sigma Sigma.
At job #2 my boss (and best friend) used to be a Delta Delta Delta (she deactivated after leaving school).
