Debra DeWitt

Buyer Rating:

Deb always had our best interest in mind. The process was remarkably smooth at every step and whenever we had any questions, Deb was there to answer them in manner that made everything so easy to understand. She kept us up date in case there were any changes and, as first time homeowners, this was very comforting. I would easily recommend her to anyone who was looking for realtor while going through their search for a home or looking to sell. - Bethany And Taylor, John January 2016

Amy Burrows

Seller Rating:

Amy, was wonderful to work with. Although no one was living in the house, she staged the house very cozily. Not only did the house move quickly, but we made a greater profit than we expected. We would definitely list with Amy again! - Kathryn Ellis December 2015

Jewel Liebenstein

Seller Rating:

Jewel was very personable and this helped to ease the tension inherent in this difficult sales situation. She had the patience of a saint when faced with the various bumps involved with the sale. - Louise Austin - Beloit, December 2015

Earl Collins

Seller Rating:

Earl had previously helped my mom buy this house. He was perfect to sell it for us.

Very happy with his diligence and hard work, plus a wonderful sense of humor - Wendy Stewart, Illinois November 2015

Mary Alonso

Seller Rating:

The Best real estate broker I had ever worked with - Josef Hose, Madison November 2015

Ronda Richter-Weber

Buyer Rating:

We first contacted Ronda when the home we were interested in was listed by her. From then on, we were quite sure that if we continued on we would like to do business with her. On several occasions, she was at a location with very little notice to show us a home. She seemed to know what we were looking for and spent a lot of time with us. She did not try to sell us on anything that we didn't want. And after all the time she spent getting us into a house, she was there at our closing. i would definitely recommend Ronda to anyone looking to buy a home, she will be right there when you need her. - Dale & Jean Burkett, Jan November 2015

Chris Mayhew

Seller Rating:

Chris was prompt and knowledgeable in all aspects of the selling of our house. He had an excellent marketing campaign. Selling in the country can be challenging as the client pool is quite a bit smaller than in town.

Chris conducted 2 open houses and the eventual buyer attended the second.

Chris was excellent at keeping us updated on any offers and conditions that arose. - John Shebelski, birchwo October 2015

Nicholas Popp

Seller Rating:

Excellent service! - El Belanger, Milton October 2015

Janine Birkhimer

Buyer Rating:

We did not have a good experience working with another broker and the managing broker at the firm (we terminated a contact after learning (from the appraiser) that the property has been misrepresented in the listing). Had it not been for Janine (who I met outside of C21), we would have let our contract lapse and started fresh with another firm. - Tresondra & Christopher October 2015

Henry Londo

Buyer Rating:

Outstanding communication and professional to a fault! Thoroughly knowledgeable and very familiar with the area, processes and pricing. What an excellent Realtor! - Paul Eckert, Madison October 2015

Penny Patterson , was a outstanding Agent . Penny Patterson worked very hard to get prompt answers to any questions

I had if it wasn't questions that as a Agent/broker she would have knowledge of. She cared enough to work over and above what

I would believe anyone in her line of work needed to. Plus she always returned my calls promptly if she was unavailable to answer

my calls. I was so lucky and happy to have her as my Agent/Broker and have and will continue to tell others about the wonderful

service she gave me and if anyone or their friends would be looking to purchase or sell a home she would give the best service.

Thank you for having such a wonderful asset working in your company also Thank You so very much to Penny Patterson for
