Connie Antoniou, a global real estate advisor and former broker-owner of two Sotheby’s International Realty offices, has long-established herself as a trusted authority in the realm of luxury real estate throughout suburban Chicagoland and southeast Wisconsin.

Her twenty-two-year tenure began in the highly competitive Hinsdale, Illinois, market—experience which eventually lead to her achieving impressive milestones as the senior vice president of sales in Barrington, Illinois, with Jameson Sotheby’s International Realty.

Along with her deep understanding of the luxury real estate market, Connie’s long-standing commitment to providing exceptional service enabled her to build a thriving career and foster meaningful, long-term relationships with her clients.  

She has represented Chicago Blackhawks players and coaches, and renowned entrepreneurs and executives, among many others.

Connie’s guiding principle is one of the key things she teaches newer agents: "Always do the right thing for the client, not what is right for your pocket, and the rest will come,” she says. “I’ve always believed that, and it has served me well.”

She was born in Iowa to Greek American parents with deep roots in the motion picture business. Connie was instilled with a stellar work ethic from her very first job at age eleven, popping popcorn for $0.50 an hour in her family’s movie theaters. Her childhood was also enriched with unique work and life experiences—like dining with Hollywood icons such as Sylvester Stallone and Donald O’Connor—that helped shape her vibrant personality and passion for exceptional service.

That passion remains as strong as ever, now over thirty-five years into her successful real estate career, and she continues to inspire and lead in luxury real estate. With a keen focus on high-end homes in exclusive golf communities and horse properties, Connie offers a bespoke concierge service that is tailored to the discerning needs of her clients.

“By taking the time to understand my clients' unique needs and preferences, I can tailor my approach to help them find the luxury home of their dreams,” shares Connie. “Whether it's a sprawling estate nestled on the lush fairways of Wynstone, or an elegant residence overlooking the tranquil waters of Lake Zurich, I navigate the exclusive communities of Barrington and beyond.”

Connie is dedicated to helping her clients find their new homes and connect with their community through her membership with GolfLifeNavigators.com, a site that assists golfers worldwide with finding their ideal golf club.

Over the years, Connie has earned well-deserved recognition in such publications as Top Agent Magazine,1 Chicago Agent Magazine,2 and Crain's Chicago Business,3 as well as The Little Blue Book for Golfers, a Sotheby’s International Realty referral group publication for golf course properties.4 Recently, Connie was a guest on the podcast Friday Fuel, hosted by the board of the North Shore-Barrington Association of REALTORS®,4 and she was interviewed by Amy Scott for Minnesota Public Radio’s renowned Marketplace.5

In addition to her other professional accomplishments, since 2013 Connie has been advocating for high ethical standards in the real estate industry as a member of the Illinois Realtors Professional Standards Committee. She has also served on the board of the North Shore-Barrington Association of REALTORS®.

In her free time, Connie enjoys playing golf and tennis, hopes to play more pickleball, and would like to get back to riding horses—she was an avid horse show competitor in her youth. More than anything else, though, Connie loves to spend time with her daughter, two sons, and her poodle. But no matter what she’s doing, you’ll likely catch her with her favorite food, popcorn!

 

Connie's commitment to her community is evident in her past involvement with the Barrington Chamber of Commerce Board and the Wynstone Property Owners Association in North Barrington, where she resides. She made history when she became the first and only woman to serve on the board of the Wynstone Golf Club.

From start to finish, Connie’s commitment to always doing the right thing by her clients and pushing for that value throughout the industry, shines through.
