John brings 19 years of experience to Rosso Commercial Real Estate Services. He has handled over $750 million in sales & leasing transactions and has been named by CoStar Group on six occasions as a “Power Broker”, both for Retail & Office transactions in the greater-Baltimore market, making him uniquely qualified as a true “full service” commercial real estate professional.

John gained an interest in real estate while attending high school, so he signed up for real estate classes at a local real estate office in Severna Park, earning his real estate license as a high school senior. Shortly thereafter while attending Anne Arundel Community College, he obtained a position with The Hogan Companies/Murphy-Hogan, learning about land and commercial property brokerage. After transferring to the University of MD College Park, John decided to continue to focus his career in commercial real estate, transitioning to Murphy Commercial Real Estate, where he remained for over a decade, prior to starting Rosso Commercial in late-2016.

John graduated with a Finance degree from the Robert H. Smith School of Business at the University of MD, where he was also a member of the national fraternity, Phi Delta Theta. In 2019, John achieved the SIOR designation, a professional achievement for highly-qualified commercial real estate specialists with a strong and sustained transactional history in brokerage, fee-based services or executive management. John is a member of ICSC (International Council of Shopping Centers) and has been active in the CCIM Program (Certified Commercial Investment Manager). Additionally, John was appointed the County Executive in 2017 to serve on the Agricultural-Tourism Commission focused on maximizing economic development in Southern Anne Arundel County while preserving its rural nature. In 2024, John was recognized by the Baltimore Business Journal as a top 40 under 40 in the Baltimore region.
