Mark Seiden Real Estate Team joins Keller Williams NY Realty Market Center as a Mega Agent Branch Office.

White Plains, NY - November 26, 2014 - ( - Mark Seiden Real Estate Team, one of New York’s top-producing real estate offices, has joined Keller Williams NY Realty in Westchester County.

"I am beyond excited to be joining with Keller Williams NY Realty! Even though I have been very successful as an independent broker in Westchester, I was always searching for ways to increase business for my team and also improve on my clients’ experience during the real estate process. The perfect answer for me was a merger with Keller Williams NY Realty. The only real estate company I know of that is truly 'agentcentric'- the agent comes first! I knew that joining forces with KW would offer the best training resources for my team and assist me in delivering the highest level of service to my clients. As an added bonus, KW’s technological advancements, innovative thinking and win-win philosophy are also in alignment with my business. In addition, the opportunities at KW are limitless! I am looking forward to training and coaching on a national level and being at the forefront of KWNY’s expansion in Westchester County. When I decided that I wanted to take my business to the next level, I knew that joining Keller Williams was not only the next logical step, but it was the only step."

Mark’s outstanding career is recognized by over 21 years of real estate service. Mark started selling real estate in 1993 and was the #1 Agent at Lois Seiden Real Estate, Inc. each year until the company sold in 1997. He was the #1 Agent at Coldwell Banker Residential Brokerage in all of Westchester County for six consecutive years from 1997 until 2002. Mark started his own agency, Mark Seiden Real Estate Team (formerly known as Mark J. Seiden Real Estate, Inc.) in May of 2003. He has been a Top 3 Agent in all of Westchester County from 2004 through 2014 for selling single family homes. He was also the #1 Agent in 2008 and 2014 in all of Westchester and Putnam Counties through a combination of listing and buyer side transactions for single family, condominium, co-op, multi-family and commercial sales.

"We’re excited to welcome Mark Seiden to the Keller Williams Realty family," says KWNY Realty Team Leader, Justine Aiello Lazzara. "This company succeeds through its people, and having Mark on our team is a huge win. As a Business Strategist, I have been watching Mark’s team for years, in awe of what he has accomplished as an independent broker. After many discussions regarding his future goals for the team, we realized early on that a merger with Keller Williams may be the right fit. I am thrilled to be assisting Mark with his team’s growth and know that the opportunities available to him at KW are just beginning!"
