Situated beside Long Island Sound and the famed Five Mile River Darien offers small-town waterfront living at the center of bustling Fairfield County. An easy commute to Manhattan and quick access to surrounding communities make Darien a popular place to settle down.
I have local expertise and global connections. This is a winning combination when I market your property to the world. My affiliation with Leading Real Estate Companies of the World further enhances my ability to network on a worldwide basis with the premier real estate firms around the world.

About me

Prior to joining the Darien Board of Realtors, Robyn had a successful career in equity derivatives at Banc of America Securities in New York City, helping high net-worth private clients manage concentrated equity risk.  As a principal, she ran a business that generated over $15MM per year in revenue.  Prior to this, she worked in fixed income derivatives at General Re Financial Products assisting Fortune 500 companies in managing interest rate and currency risk.  The skills that made her successful assisting clients in these asset classes, have translated well to the real estate market.
