Karen Hagen

In guiding Fairfield County buyers and sellers to success, Karen Hagen has garnered extensive market expertise while building meaningful relationships with her clientele and community. Karen’s impressive talents and track record are due, in part, to her innate ability to connect with clients, listen to and understand their goals and build a clear plan to achieve their objectives. Satisfied clientele rave about her responsiveness, professional service, tenacious negotiation skills and priceless guidance. Karen understands that buying or selling a home can be daunting, so she continually strives to minimize stress, maximize value and make the entire process as enjoyable as possible.

Karen's real estate career began in 2012; she quickly rose to the top five percent of agents worldwide. Before real estate, she spent nearly a decade with the National Football League working on player programs, international activities and corporate sponsorships. She credits the experience of working with professional athletes and high-level executives with forming her diplomatic, solutions-oriented style. Laser-focused and patient, Karen is the calm at the center of the storm. Whether in football or real estate, her successful business philosophy is simple — treat others the way you want to be treated. It's no surprise she's cultivated a tremendously loyal repeat and referral client base.

Karen and her husband, Colin, raised their two children in Weston, lived in Westport and now reside in Fairfield. Always a community volunteer, Karen’s interests expanded as her children grew and she developed her business. She was chapter president of BNI’s Westport Entrepreneurs and has recently become a board member of the Mid-Fairfield County Association of Realtors. On a broader scale, Karen is a founding member of the National Association of Divorce Professionals (NADP). Working with other licensed professionals in NADP, Karen has gained a better understanding of the unique challenges presented by divorce, enabling her to more effectively serve clients facing this situation.

An outdoor enthusiast, Karen spends her free time on walking and hiking with her husband and their Golden Retriever, Brody or on the courts. An avid tennis and paddle ball player, Karen also serves (pun intended!) on the Tennis & House committee at Aspetuck Valley Country Club.
