Mike Kollmansberger - ABR, Broker Associate, CSRS, SFR

Mike did an outstanding job of providing information on homes as they entered the market. When we wanted to set up a showing, he responded promptly and set them up very quickly. Mike also did a great job of talking through how to write a quality offer that would give us the best shot of having it accepted. When it came time to sell our home, Mike was very thorough in telling us how to work through that process and ultimately we received significantly over our asking price. Overall, Mike did a fantastic job guiding us through the process of buying a new home and selling our old home.

Mike is excellent, really enjoyed working with him. I would highly recommend him!

Mike was fantastic to work with. He kept me well informed.

Mike was awesome! He was super patient with us and helped us get into the best house! He was very helpful in terms of understanding the market value of each home, and offering the right amount for each home we put bids in for. Mike was extremely knowledgeable, and taught us many things along our home buying journey.

Mike Kollmansberger was simply an amazing agent! Our house sold very quickly with a solid, over asking offer from the second family to request a showing. It was a smooth sale, without drama or stress. All our rookie questions were quickly answered, and Mike was always ready with a genuine smile, and a knowing nod of assurance. He was a total professional, but with a light and caring touch. I am so glad we had Mike as our agent, and I highly recommend his services to anyone either thinking of selling their home, or interested in finding their dream house. Thanks Mike!

I already did this

Mike is professional and reliable. He handled everything with integrity. A job well done!

Mike assisted with the sale of my mother's home back in 2019. I thought he had done a nice job. I used him for the sale of my wife and my home. Again, I felt he did a great job! Hopefully, he can assist my neighbor in the sale of his home.

Mike is exceptional, professional and customer-friendly. Since August 2024, he sent us listings and helpful information to prepare us for house-hunting in Oconomowoc and surrounding communities to assist us with our move from California. He guided us through an aggressive 4-day search in April 2025 to find the right home in the right area at the right price, and worked with his contacts to get us the right mortgage broker to close our deal. Mike's swift and thorough responses to our questions and needs guaranteed we had the right information throughout our purchase process, and he stays in communication with us still. Our initial thought was that we found a great realtor, but in fact we found our first friend in Wisconsin. We give Mike our sincere gratitude and highest recommendation for others who might be so fortunate as we were to work with him.

I am very please with Mike Kollmansberger. He show excellent knowledge to the whole process of the sale, trust him to do the best as he does so well. Great communication, care and kindness with both parties involved. Went out f his way to satisfy the sale of my condo. I do really appreciate his service. God bless you!
