About Colleen
A lifelong Westchester resident, I have lived and worked in the area for more than two decades. After graduating from college, I spent 11 years in Manhattan working for AOL Time Warner, where I built a strong foundation in sales, marketing, client service, and contract negotiation.
In 2005, my husband and I moved to Pelham to raise our family, and in 2010 I began my real estate career. Since then, I have enjoyed working with buyers and sellers throughout Bronxville, Pelham, Larchmont, Scarsdale, Rye, and surrounding Southern Westchester communities. I work across a wide range of price points and property types and handle both listing homes and helping buyers find the right place for them.
Over the years, I have been fortunate to build lasting relationships with clients, many of whom return or refer friends and family. I help sellers with pricing, preparation, and getting their home ready for market, and I guide buyers through each step of the process from search to closing.
I love what I do and feel grateful to be part of such a strong Westchester community. My goal is always to make the process as smooth and positive as possible while helping my clients reach a great result.
