Professional Summary

Teaming with David Bercu and Jonathan Kohn, principals in Colliers International’s Industrial Advisory Group, I specialize in assisting owners and tenants in the leasing, sale and development of industrial properties. I focus my work primarily in the O’Hare and I-90 submarkets, giving my clients extensive market knowledge.  Since joining Colliers in 2014, John has been involved in over 90 transactions valued at more than $100 million in consideration and totaling over 3 million square feet.

I began my real estate career as a commercial broker with McLennan Companies, where I worked with owners, tenants, buyers and sellers throughout the Chicago area.

Prior to working in real estate, I spent more than 15 years in the networking equipment industry working for Tellabs and Marconi Communications. I held senior-level positions in sales, product line management and mergers and acquisitions, working on both domestic and international assignments.
