Michael J. Hejna is the Managing Broker for Gundaker Commercial Group, Inc. (GCG).  With a background in real estate financing and development, his responsibilities include overseeing the functions of GCG as a company, with a primary focus on organization and capital formation of developments and joint ventures.  He manages all of the affiliated entities associated with GCG, consisting of 30 separate, but affiliates business entities, engaging GCG’s Asset Management, Brokerage, and Development Divisions. Mike has grown GCG’s portfolio to 100 projects and $750 million of commercial and residential real estate development in Missouri and Illinois, as well as across the United States and Puerto Rico.  A portion of that portfolio was a national platform for retail development with Fortune 500 firms whereby GCG offers design/build and sale/leaseback opportunities to  corporate relationships. A portion is land development leading to lot sales, retail, industrial, office, and multi-family projects.
