Our Team

Born in the small town of Sullivan, Missouri, Geoff studied history and received his Master’s Degree in American History from Western Carolina University. Geoff credits his mother working in Sullivan City Hall for most of his childhood for his interest in how the government works with its people and the built environment. Before transitioning to the real estate and market analysis industry, Geoff taught history, politics, and economics at the high school level—he uses the local politics and economic concepts he taught to his students in his everyday work.  

At KB Advisory Group, Geoff enjoys being part of the growth and development of our city, region, and state. As the President of KB Advisory Group, he also enjoys creating and leading the team and helping the staff find professional growth and satisfaction.  

Some of Geoff’s personal career achievements include being part of the early planning efforts for many successful developments and redevelopments around the Southeast. Some of his personal favorites include the Turner Field, now GSU Stadium, area revisioning, as well as the creation of the new portion of Alpharetta’s new downtown area, and the creation and evolution of Sugar Hill’s downtown area in Gwinnett County. His biggest highlight was playing a leading role in the creation of the Westside Atlanta Land Use Action Plan in 2016.  

When he’s not working, Geoff enjoys spending time with his family (including his dogs) in the North Georgia mountains and at Lake Burton. He is also a proud supporter of the 2018 MLS Cup Champions, Atlanta United. Next time you see him, be sure to ask him about his college basketball days, too! 

Jonathan Gelber was born in Paris, France when his parents were stationed for business. His family came back to the United States and moved to Los Angeles when he was 1. Jonathan earned a Bachelor of Arts degree from Reed College in Portland, Oregon, where he studied Architectural History.  He then went on to receive a Master of Science in Urban Planning from Columbia University in New York in Atlanta, followed by a second Master of Science in Real Estate from Georgia State University in Atlanta.  

Jonathan currently serves as Vice President of KB Advisory Group and he most enjoys the ever-changing challenges of consulting in his 12 years with the company. He has never had the same day twice, and always finds new projects, places, challenges, partners, clients, and communities to work with. 

Jonathan’s personal career highlight was helping to start the New York City bicycle network in 1992 that now sports over 1,300 miles of bike lanes. Other notable highlights include seeing the Atlanta BeltLine and everything around it blossom over the last 20 years.  

Something people are surprised to learn about Jonathan is his five-year career as a professional chef in the mid-1990s where he worked his way up to Executive Chef. He came back to planning and consulting after the birth of his first child.  

When Jonathan is not working, he enjoys spending time building and perfecting his elaborately cascading waterfall and fish pond network in his back yard stocked with over 30 “Shubunkin” fish, which his wife affectionately refers to as his “Shubunkiverse.”
