Mike Ertmer, Realtor with BHGRE Special Properties

Mike’s journey into real estate started long before he sold his first home. With a background in the travel industry dating back to 2004, sales and client relationships have always been at the core of his career. After years in travel marketing and technology—living in cities like Milwaukee, Appleton, and Berkeley—he eventually found his way to Green Lake in 2017. It didn’t take long for him to realize he was home.
For Mike, real estate is all about connection—matching people with homes and communities that fit their lifestyle and dreams. Whether he’s helping buyers find their perfect lakefront getaway or guiding sellers through passing their property to the next generation, Mike brings energy, strategy, and genuine care to every transaction. He’s proud to represent some of Green Lake’s most remarkable homes and is deeply invested in the community. As a member of the Green Lake Chamber Board of Directors and a familiar face at local events, he's proud to serve his community and more.
