"Diane Sugden and Jackie Syvertsen are an amazing team! Their support and clear communication, willingness to answer questions whenever they arose, and deep knowledge of real estate in our community all helped optimally position my house for sale. I have known Diane for over 10 years as she successfully guided friends through this stressful time, and could not have been more pleased to have her expertise to sell my own house. I highly recommend Diane and her team at Windermere!

"Diane Sugden is a fantastic agent and person. She always has a smile and was very positive during the buying process. Being from out of state, I could not have bought a home without her. Diane always responded to my questions and was very honest about possible problems with homes we looked at, both online and in person. She is a great guide, and Windemere is lucky to have her."
