About Us

“Helping owners and users of commercial, industrial, retail, office, investment and development real estate in the New York and New Jersey Metropolitan area create value by providing expert brokerage services coupled with cutting edge market knowledge.”

Specialization + Proprietary Real Estate Data + Experience = Expert Real Estate Advice

The professionals at Greiner-Maltz recognize that we owe our success to our specialization in the geographic region and concentration in only commercial, industrial and retail real estate. This concentration of intellect of over 60 years has created a proprietary database which not only forms the basis for creating more transactions than any of our competitors but is also called upon by appraisers, bankers and city agencies when they need "help" with the market. There is good reason why the name Greiner-Maltz has become synonymous with commercial and industrial real estate in the New York and Long Island metropolitan areas.
