CHICAGO OFFICE SPACE TENANT REPRESENTATION
We Represent Tenants. Never Landlords.
Unlike full-service commercial real estate firms, we don’t represent office landlords, own buildings or manage properties. Our only client is the tenant.
Most tenants overpay because they negotiate too late or don’t have real leverage. We fix both.
Most leases run above market. 12 to 18 months before expiration is the time to act; inside 6 months, still call. The landlord pays our fee.

THE FOUNDERS
Two Tenant Advisors. 80+ Years Combined. Tenant Only Since 2004.
Tom Koelzer and Dave Ven Horst spent nearly two decades at one of the largest commercial real estate firms in the world. They kept seeing the same thing: tenants at the table with a broker who also represented their landlord.
In 2004 they left and built a firm with one rule. They haven’t represented a landlord since — 2,000+ office leases negotiated, every one of them for the tenant.
