He joined the staff of Hart Corporation, a national real estate firm, headquartered in Southampton, PA, specializing in industrial real estate. He went on to become a managing partner for the Trammell Crow Company. In 1980, Barry started his own company, and over the years he has grown this company to its status today as one of the largest and most successful full service commercial real estate brokerage firms in the Philadelphia/Southern New Jersey Metro area.

Celebrating over 25 years of service, NAI Mertz is one of the most professional companies in the area, with more brokers holding their SIOR designation than its competitors.

Altogether his staff totals 39 including 28 sales staff.
