Siderow Commercial Group, a boutique Manhattan commercial real estate brokerage, is expanding its ranks with the addition of two industry veterans.
Established NYC commercial insiders, Alexander Altman and Marty Kuper both have a history of Manhattan leasing, representing tenants ranging from an international restaurant group to celebrity businesses and tech startups.
“Commercial brokerage in NYC is truly a challenge and an acquired art form in its own right. Breaking into it and becoming a true polished pro isn’t accomplished within a year or after one deal; it takes a special mix of drive, perseverance, business savvy, relationship building skills and a thirst for Manhattan business and lifestyles,ˮ said Bradford Siderow, Founder & CEO of Siderow Commercial Group.
“We’re thrilled we met two possessing this mix in Alex and Marty, who also see in Siderow Commercial Group as a brokerage where they can grow their careers.”
Siderow Commercial Group, focuses on tenant and landlord representation and works closely with its clients on real estate strategy.
