Tess Eby

CHIEF OF STAFF – She/Her

What’s your why?
Super simple – helping anyone and everyone who has the motivation to better themselves! I came from a background that provided me many opportunities to both succeed and fail, and the ultimate option of what path I wanted to take was up to me. Here at Avenica, we are finding ways to demonstrate the type of potential that you can’t see and focus more on what people have the potential to do vs. what they have done. I get excited over being able to go against the grain and help forge a new path into hiring, culture, and experience — which is what we do every day at Avenica.

Tess graduated from the University of Illinois at Edwardsville with a B.S. in Applied Communication Studies.
