|Mark got started in the industry in 1993, working for his mother’s real estate company in Westchester County, NY. Three years later Coldwell Banker purchased their firm, and for the next six years Mark remained one of the most prolific agents in the county.|
In 2002 Mark ranked as the #2 agent in Westchester and Connecticut combined. In May of 2003 he opened his own agency, Mark Seiden real estate. After opening two more Real Estate companies in early 2004 – El Sueño Americano Real Estate, and MarqueeBrokers Real Estate – Mark finished that year stronger than ever, closing over $50 million in real estate sales on nearly 100 transactions.
As of late 2005, Mark has closed in excess of $40 million on 70 transactions. Since his departure from Coldwell Banker, his business has increased over 20%, and between all of his companies, Mark utilizes the skills of four exclusive buyers agents and currently has over 50 active listings. As the undisputed #1 agent in Westchester, Mark outsells the other 8,000 licensed agents in the county by a considerable margin.
