Jay Wilewski - Real Estate Agent at Jameson Sotheby's International Realty – Barrington

Local Expertise. Global Connections.

Jay Wilewski has built a successful real estate practice by prioritizing honesty, character, and integrity in his interactions with clients. He began his career in 2007 as a credit analyst with Wintrust Corp in Barrington, Illinois, and the economic recession of 2008 reinforced the importance of these principles to him.

Years later, Jay moved from Barrington to Chicago. After working as a leasing consultant in the competitive Gold Coast area of Chicago, Jay decided to become a full-time real estate broker. His success in this dynamic market was fueled by his strong listening skills, in-depth knowledge of the real estate market, and persistence, as well as his commitment to honesty and integrity. These principles continue to guide his work and have helped him build a thriving real estate practice.

Jay joined The Connie Antoniou Team at Jameson Sotheby's International Realty in 2017. The team was the top performer in closed volume among the three North Shore offices of Jameson Sotheby's and a leading player in the Barrington area real estate market. Years later, Jay decided to start his own real estate business with Sotheby's and intends to apply the same principles, dedication, and knowledge that helped the team achieve its top ranking.
