Alan is often thought of as "an exclusive broker" as a result of his tremendous success in marketing seller's properties. "The right price is the key to garnering the highest sale price in the market," he says, "and I try to find that price by analyzing past sales with the current market trends, buyer base, and competition and then tailor the marketing plan to fit. I also enjoy a place of trust and respect within the brokerage community which helps the transaction go smoothly."

Alan moved to New York in 1980 and has called the Upper Westside home since 1983. A large portion of Alan's business has been on the Upper Westside with a focus on Riverside Drive. Early in his career he wrote and distributed his "Riverside Drive Market Availability Report", and as a result did so much business that Barbara Corcoran crowned him the "King of Riverside Drive." In 1994 he sold his first townhouse, which opened doors to another facet of New York living. His fascination led to his second specialty, which culminated in his becoming the Director of Townhouses in Corcoran's Westside office.

In 2010 Alan officially launched "Alan Berger's 5% Promise" in which he contributes 5% of his gross commission from each sale to a New York City based charity. The list consists of charities that provide food, shelter, and public enjoyment for New Yorkers. The customer or client then chooses from the list to determine where the money goes.
