About Constance Y.

I have been, and will always be, a marketing rebel. Helping homeowners in the upper bracket find or sell their Luxury Lifestyle Home is where my expertise shines. My passion and knowledge is in distilling the Essence of a magnificent home and conveying that Essence to the most qualified buyers in the world.

When I bought my first Sotheby’s Real Estate office in Barrington, right outside the Wynstone Community in North Barrington, I was flying high after my previous 20 years with Brush Hill and Adams & Myers, in the highly competitive Hinsdale market. I was consistently in the top 5 where I sold, or rented, many homes to the Blackhawks players and coaches in addition to the Who’s Who of Chicago Executives many of whom I consider friends to this day. After moving North in an attempt to get a fresh start with my family, I thought that my success in Hinsdale would easily translate into the Barrington market. Boy was I wrong… and not just because of the different market, but the entire real estate paradigm changed. It was 2007 and the economy was collapsing…

Since then, I figured it out and have been back in the Top 5% of Chicago Agents ever since. I even opened my second office in the Village of Barrington in 2012 to meet the local demand. So I opened another International Boutique office offering the same concierge level brokerage services that the discriminating sellers and buyers in the Barrington’s were seeking.

With this service model working so well, Jameson Sotheby’s, asked us to merge into their large organization with the promise to maintain the same level of service and boutique feel but with many more resources and staff to take Luxury Lifestyle Marketing for our Barrington and Northwest Suburban Chicago clients to a whole new level. Very exciting.
I was born in Dubuque, the proud daughter of two multigenerational Greek families in the Motion Picture Business. I’ve met and dined with many of the Hollywood greats including Sylvester Stallone, Harry Belafonte Jr, and Kevin Costner to name a few. My love for popcorn remains to this day and I often reminisce about making barrels full of this “white gold” for hours under my father’s employ.

I have always worked hard to earn a living, as I am sure did you; and I am so thankful for where my life’s journey has taken me. I have a heart to help the most people I can, to protect their home values and to get the most they possibly can within the constraints of a fickle market.

I painstakingly work with people wishing to sell their homes to determine the current market range and allow them to choose the listing price within that range based entirely on their level of motivation to sell within a certain timeframe. And then I promote the hell out of it both locally, online and in print, to the most qualified buyers in the world.

I invite you to review my marketing strategies and the tools I use to gain the most online showings as I possibly can and to draw
