Dianne - this lady gets it done!! She anticipates, listens, and most of all fights for her clients no matter what the circumstances. The whole Keller Williams team was a delight to work with and truly made the impossible possible ❤️🏡

We worked with Dianne to sell our home on Green Street in Lehighton! The stars truly aligned and she had a buyer who was very interested in our home. The way Dianne handled everything was absolutely perfect, very attentive and also she walked us through the process, step by step. Couldn’t have had a smoother and longer closing process to accommodate major life changes in our family! Would absolutely work with her again as she is absolutely AMAZING! In addition, important to know, she knew the areas, the ins and outs and also ensured that all of the right things were done throughout the process including appraisal and inspection activities. Even sent reminders on things that one may not know about or could easily forget. Highly recommend Dianne and Keller Williams.
