Managing Broker
Real estate has been part of the Ioannou family since 1976, when Theodore Ioannou began his career in Chicagoland. Today, Nicholas works alongside his father as Managing Broker, running TGI Realty as a family-owned and operated brokerage built on knowledge, care, and tradition. Since joining in 2020, Nicholas has guided clients through a wide range of needs—from investment properties to personal homes. In addition to brokerage, he also manages more than 30 residential and commercial units through Cambridge Property Management, giving clients access to truly comprehensive, full-service real estate solutions.
