Pete Kosanovich


A career entrepreneur, Pete has participated in a number of unique business opportunities. One of the most fulfilling has been Alter Brewing Company. Pete introduced David Yob and Mark Hedrick in 2013, the three of them went on to found Alter Brewing Company in 2015. Pete continues to utilize his relationships to augment the growth of the Alter footprint.

Growing up in Lombard working at restaurants and bars, Pete learned the value of hard work at a very early age. Upon graduating from Purdue University in 1993, he set out on a career of betting on and believing in himself. Pete got his start on the trading floor of the Chicago Mercantile Exchange. Over time, he founded and ran a number of companies in the financial markets. In 2009, he integrated these companies into Trean Group, LLC and is currently the CEO.

Family is very important to Pete, he has been blessed with two sons and a daughter. His hard work has allowed him the ability to attend almost every game, meet or activity that his children are involved in. Sometimes he is asked to watch from the next field/court over, but he is in attendance none the less!

Executive Leadership
