Donna & Dan


"Donna Hermsen and Dan O'Brien are professional, knowledgeable and responsive. We felt that they were willing to devote much time and effort to selling our home, and they were successful. Plus, both of them have great warm and friendly personalities -- which helps to relieve much of the stress associated with home-selling. We were proud to have them represent us in our home sale. John & Mary Daggett
My husband and I relocated from Florida to Wisconsin. As part of my relocation package, Donna Hermsen was assigned to us by my company. We flew to Madison for a long weekend to look for a new home. I was 7 months pregnant, we did not know the city very well and we were in a rush to select a house. Needless to say, we were not expecting a very positive experience. Much to our delight, Donna could not have made our home buying experience any better. We saw almost 50 houses in 3 days. Donna sent us potential houses in our price range weeks before we arrived, she narrowed down the search so that we made the most of the short time we had in Wisconsin and was very prepared by the time she picked us up on the first day. Donna knows the Madison area quite well. She knew where all the schools, parks and shopping areas were and was honest about the houses she felt would not be good for investment purposes. She was flexible and patient as we went through the same houses again and again until we made a decision. She even sat and advised us for hours, with both of our extended families, while we hemmed and hawed over house details. Throughout the entire home-buying process, Donna was our favorite person to work with. She was flexible, honest, friendly and her expertise spanned beyond real estate. She helped us with many other aspects of owning a new home as well. I have recommended Donna to everyone who moved into Madison area. Our relationship continues to this day 7 months after the house was purchased. I am happy to give more details to any potential clients. Katie & Tim
Donna & Dan worked extremely hard and they never slowed down or let up on showing my home. Donna & Dan go above and beyond when you list your property with them. They advertise your house in every possible publication and they don't let up in listing it continuously. Donna & Dan have open house showings more that any other Realtor, and they are ALWAYS available. Donna & Dan really showed their knowledge, expertise and professionalism when the offer to buy came in. They looked out for my interests and they were creative in drawing up the counter offer. This really impressed me as countering is a risky move but they knew what to do for me and not lose the sale. Donna & Dan are "true blue" and honest. You can trust them with every detail. I would RECOMMEND Donna & Dan for a REALTOR. Especially after my experiences with previous Realtors. They are the ONLY REALTOR. Donna & Dan follow through 100% with everything they say they will and they are committed to representing the interests of their clients. - Morgan Mortensen 608-233-5723 Morgan Mortenson
Donna was recommended to us by friends whom she had helped with a difficult house purchase a few years ago. When it appeared their purchase would fall through at the last minute, Donna managed to save the sale and our friends' sanity! Our own house purchase was not nearly as dramatic; but as first-time home buyers, we were extremely grateful for all the advice and support Donna provided us. She was always cheerful, incredibly knowledgeable, responsive and understanding. She also made sure we knew what we were getting into in terms of budgeting for a mortgage and other related costs. We were fortunate to find a beautiful place that we fell in love with after only a couple of weeks searching, Donna remained constantly in touch with us during the closing process and afterwards. She even recommended a wonderful home inspector who was extremely helpful in spotting a few things that needed to be corrected by the seller before we closed on the sale. In addition to her professionalism and knowledge, Donna also regularly goes above and beyond for her clients. Even a year after the sale, she keeps in touch with us. She even gave us a Christmas wreath for our front door, as well as the best housewarming gift we got- a handmade kitchen crock personalized with our names and a picture of our home. It's these personal touches that set Donna above all other realtors we've encountered. We can't recommend her enough! Agent response V & G
Dan and Donna are a dynamic team. The three of us worked together to make informed decisions about the preparations we made for my sale; the house was listed less than a week and our asking price was near spot-on the final sale price. Donna's attention to the particulars complemented Dan's commitment to helping see the project through. I wouldn't hesitate to use them again nor to send my closest friends their way. Kevin Hinz
