Commercial Real Estate’s Leading Independent Information Provider Recognizes Market’s Top Leasing and Sales Brokers

Annapolis, MD – John Rosso, founder of Rosso Commercial Real Estate Services, has been named a 2016 CoStar Power Broker TM by CoStar Group, Inc. (NASDAQ: CSGP), the leading provider of commercial real estate information, analytics and online marketplaces. This annual industry award recognizes distinguished professionals in commercial real estate brokerage by highlighting the achievements of the firms and individual brokers who closed the highest transaction volumes in commercial property sales or leases in 2016 within their respective markets.

This recognition comes less than a year after the founding of Rosso Commercial Real Estate Services. John is the only “top office leasing broker” based in Anne Arundel County & Annapolis to be named by CoStar Group in this category.

Rosso qualified as one of the top commercial brokers in the greater-Baltimore market based on the total commercial property lease transactions he closed during the year of 2016. To be selected for this honor, Rosso’s overall transaction volumes were evaluated by CoStar against other commercial real estate brokers active in the region, and subsequently ranked among the top brokers in the market.

“Anne Arundel County is vibrant and growing, with businesses of all sizes in ‘expansion-mode.’ There is robust new office, medical, retail and multi-family projects in the pipeline, and a strong sense of optimism amongst our clients. I’m thrilled to be part of this exciting growth as it continues into 2017,” said Rosso. “I’m honored to be recognized by CoStar, and look forward to building on this success.”

“With such an active year in commercial real estate, CoStar is proud to honor the firms and brokers who perform at the industry’s highest level,” said CoStar Group founder and CEO Andrew C. Florance. “These industry leaders deserve to be recognized for their hard work, expertise and superior deal-making abilities.
