Coldwell Banker Realty - Gundaker


Who We Are:


Real Estate runs in the family: Steve began his career working with his father, Julian, in commercial real estate after graduating from Tulane University in New Orleans.  Soon after, he began working for Coldwell Banker Gundaker in residential real estate. For over 30 years, it has been his absolute pleasure to guide people through the process of buying and selling real estate. As a top-producing real estate agent, and over $560+ million in closed sales, Steve has developed a reputation as being a realtor second to none. Amassing accomplishments such as being awarded St. Louis Business Journals “Top Ten List” in real estate, Ladue News’ “Top Men In Real Estate”, and earning two of the most coveted designations awarded to top producing sales associates in residential real estate, Graduate Real Estate Institute (GRI) and Certified Residential Specialist (CRS), separating him from 95% of the agents across the country.

Steve and his wife of forty-three years, the former Julie Optican of Saint Joseph, Missouri, have two sons. Andy is a 1999 graduate John Burroughs School and a 2003 graduate of Emory University.  He works in Private Equity in Atlanta.   In 2014, Steve was thrilled to announce that their second son, Joe, would join Steve in the real estate business!
