Michael Ertmer

Meet Mike Ertmer Real Estate Broker | Better Homes and Gardens Real Estate 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. Each day in real estate brings something new—new people, new challenges, new stories. That’s what keeps Mike inspired. 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, Mike’s passion for Green Lake goes far beyond the business. When he’s not working, you’ll likely find him at the gym, on the boat, or out on the golf course. A traveler at heart, Mike loves exploring new destinations—especially when it means reconnecting with friends in places like Florida or California. But no matter where he goes, Green Lake will always be home base.
