Founded by Walter N. Propps SIOR, CPA, in 1972 as a development and brokerage company, Commercial & Industrial Real Estate, which became Commercial Brokers LLC, began as a two person firm.  As demand for specialized properties increased, a construction company was added.  This gave Commercial Brokers the ability to build office and warehouse properties and perform most functions in-house.  Commercial Brokers represented clients better than other firms by constructing facilities to their exact specifications.  After the return of Nick Propps in the late 1990's, the firm expanded further as additional properties were acquired, new team members were hired and the firms capabilites were expanded.

Some of the properties constructed or developed by Commercial Brokers include multi-tenanted flex, office and warehouse buildings, a fully refrigerated warehouse for Kolker Poultry, headquarters for Orkin Pest Control and a 180,000+ sq. ft. paper warehouse with rail service for Parson's Paper Company.
