Three Generations.
One Mission.

Third Coast Luxury is a premier real estate team on Chicago's North Shore, led by Coco Harris and Julie Bradbury Miller — two accomplished brokers united by friendship, shared values, and a deep commitment to their clients.

For Julie and Coco, real estate is more than a profession — it's a family calling. Both grew up watching their mothers build extraordinary careers in the industry, and today they take great pride in watching their own children, Grace Miller and Alex Harris, carry that legacy forward as third-generation realtors.

Together with their team of nine seasoned agents, they bring unmatched local expertise, white-glove service, and genuine passion to every transaction on the North Shore.
