Setting the Standard in Chicago Luxury Real Estate
With over 25 years of experience and more than $1 Billion in closed sales, Nancy has built a career defined by excellence, integrity, and results. Recognized as the #1 Agent at Jameson Sotheby’s International Realty, she continues to raise the bar in Chicago's competitive real estate market.
A consistent Chicago Association of Realtors Top Producer since 2005, Nancy serves as Senior Vice President at Jameson Sotheby’s International Realty, where she specializes in luxury homes, new developments, and high-end buyer and seller representation. She is the #1 Luxury Agent across the Gold Coast, Streeterville, and River North, with an elite client base that includes professional athletes and ultra-high-net-worth individuals.
Clients praise Nancy’s “start-to-finish” approach, hands-on involvement, and ability to simplify even the most complex transactions. Her reputation for professionalism, strategic insight, and results-driven negotiation has earned her the trust of repeat clients and the respect of peers citywide.
Nancy’s deep knowledge of Chicago’s neighborhoods—shaped by 27 years as a resident and North Shore upbringing—makes her an invaluable resource. Whether advising on lifestyle, location, or long-term value, she offers thoughtful, data-driven guidance that empowers clients to make smart decisions.
Nancy’s luxury development expertise is unmatched, having led the complete sellouts of iconic buildings like No. 9 Walton and represented all 77 residences at One Chicago. As the founder and former Managing Broker of JDL Brokerage, she oversaw more than $700 million in new construction sales, giving her clients an edge in both resale and pre-construction opportunities.
Before real estate, Nancy earned a business degree from the University of Wisconsin–Madison and worked in marketing and advertising at global consulting leader Accenture.
She lives in Chicago’s West Lakeview neighborhood with her husband, three children and golden retriever.
