Leadership & Market Impact

Franz and Evan are not only top-producing agents—they are co-owners of Coldwell Banker Islands Realty. In 2017, they purchased the company together, building upon Islands Realty’s strong legacy and guiding it into continued growth. Their leadership has helped grow CBIR as the #1 real estate agency in Grand Isle County, holding a 28% market share.

Their success reflects a deep commitment to the Lake Champlain Islands and Vermont community. With decades of combined experience and firsthand knowledge of the nuances of lakefront and Champlain Island properties, they provide clients with a level of insight that goes beyond the transaction.

What makes these recognitions especially meaningful is that they represent both individual achievement and collective strength. The example Franz and Evan set through professionalism, collaboration, and mentorship elevates our entire brokerage.

Congratulations to Franz and Evan on an exceptional 2025. We are proud of all that was accomplished this year and look forward to continued success in 2026.
