Dave was proactive in getting our places sold and we felt like we were a priority.

Eliza Street was the second property that Dave sold for us. My partner and I had multiple investment properties in Green Bay that we needed to sell and little to no time to manage the process. We worked with Dave Peot and couldn't have been happier with how it turned out. Dave was proactive in getting our places sold and we felt like we were a priority. He used his relationships and connections to bring in strong buyers for both of our properties and was able to secure our asking price on each of them. My partner and I had very minimal involvement and were able to entrust Dave to manage the whole thing. I would certainly use Dave again in the future.

Todd went above and beyond to make sure I was able to purchase my dream home.

I would highly recommend Todd to be YOUR realtor.


Todd went above and beyond to make sure I was able to purchase my dream home. Todd met with me immediately when I was interested in a home, and he communicated with me through email, phone calls and texts. He was always there for me whenever I had any questions. Once my offer was accepted, Todd met with me the following day to get my house listed. He talked me through exactly what would happen and how other agents would contact me for viewings of my home. Todd knew my house and area very well. Within days I had an offer above asking price. I feel very fortunate that Todd was my realtor. He made my transition from one home to another very easy. Todd is the perfect real estate agent and I highly recommend him.

I certainly would retain Dave again with any future real estate transaction!

I've had the good luck to work with Dave twice ... He sold me my first house (in DePere) and 10 years later Dave helped me sell the house when I had to move due to progressive disability. The house sold within days, I received an initial bid ABOVE the asking price, and I only had to make a decision now and then and sign papers. When the inspection took place I was disappointed because the cost was going to be great, but Dave negotiated it down to a more reasonable amount. I certainly would retain Dave again with any future real estate transaction!

Working with Jane Jadin to sell our mother’s home was the most pleasant, professional real estate experience I have ever had!

Working with Jane Jadin to sell our mother's home was the most pleasant, professional real estate experience I have ever had - and I've had a few! Jane kept my three siblings and I informed every step of the way. Her staging of our home was simply outstanding as was her style of interacting with both potential buyers and the four of us. I was thinking that in a hot Green Bay real estate market, we could try to sell the home on our own - Well I'm so pleased we DID NOT go solo in this effort. Selling a property today has so many more layers than even five years ago. Having Jane Jadin in you corner is an incredibly valuable asset! Thank you Jane for making this process painless.

This was the most pleasant, professional real estate experience I have ever had.

Recently Jane Jadin helped my siblings and I sell our mother’s home. I’m here to report that this was the most pleasant, professional real estate experience I have ever had - and I’ve had a few! Jane kept my 3 siblings and I informed every step of the way. Her staging of our home was simply outstanding as was her style of interacting with both potential buyers and the 4 of us.

By the way, before we hired Jane I was thinking that in a hot Green Bay real estate market, we could try and sell the home on our own - save ourselves some money. It really felt like properties were selling themselves. Well I’m here to say that I’m so pleased we DID NOT go solo in this effort. Selling a property today has so many more layers than even 5 years ago…and having Jane Jadin in your corner is an incredibly valuable asset!
