When Domenica Koch moved to Lake County, Illinois, in 1994 to raise her family, it laid the foundation for a real estate career that has now spanned more than three decades. Living directly within her core markets gives her a firsthand understanding of the residential landscapes across Lake, McHenry and Cook counties. This deep local familiarity informs how she guides clients through the region she calls home.
Koch specializes in single-family homes, townhomes and condos, working with first-time buyers, move-up buyers and investors across the northern Illinois suburbs. Her client base is built almost entirely on referrals from past clients and long-standing business relationships. Most people who call her were sent by someone who has already successfully gone through the process with her.
Navigating a shifting real estate environment requires transparent communication, which Koch establishes through initial meet-and-greet consultations with buyers and sellers. These strategy sessions outline her working style and clarify milestones, educating clients on what to expect during the transaction. Known for being an accessible, hands-on representative, she uses active listening as a key component of her customer service.
Koch received the @properties Christie’s International Real Estate Business Impact Award in 2025 and was featured in Chicago Real Producers magazine earlier that year. In addition, she is a member of Women Belong, a business networking organization that has broadened her connections with local business owners throughout the area.
Born in Switzerland and raised on Chicago’s North Side from the age of three, Koch is planning a Rhine River cruise this year that returns to her birthplace. On social platforms, she documents homeownership milestones, publishing client case studies to give prospective buyers and sellers a clear, relatable view of the market.
