We were thrilled to have Peggie working for us in Illinois while we were house-hunting from Michigan. She knew exactly what was important to us and attended a walkthrough with us virtually and she was very honest with her opinions of properties - she wasnt just out to make a buck. She wanted us to be somewhere we would like. MUCH appreciated.

We're fortunate to have been guided by Peggie in securing our forever home! We have very specific asks and taste, and Peggie was always patient with us in fine-tuning search criteria. She always responded to our questions and requests instantly, and was always thoughtful in her response. Months of countless house tours later, we found THE HOME and entered the next phase of offer and negotiations. This was where her experience, knowledge and creativity shined. Peggie led us through the process all the way to closing day. In this fiercely competitive seller's market, we wouldn't have secured the house without her expert intervention. We're forever grateful to Peggie!

We cant say enough great things about Peggie! She first entered our lives six years ago as the sellers agent for our first home, and she was so wonderful to work with that when it came time to sell that home and find our dream house, we knew exactly who to call. This time around, we needed a home that was more accessible for our sons wheelchair, and Peggie went above and beyond to find the perfect fit for our family. She was patient, understanding, and incredibly knowledgeable, helping us navigate both the sale of our old home and the search for a new one that met our needsaEUR"at a great price. On top of that, Peggie had fantastic insight when it came to staging and prepping our home for sale. Her guidance helped us maximize its appeal, and we were thrilled with how smoothly the process went. She was always available to answer questions, offer advice, and make everything as stress-free as possible. If youre looking for a real estate agent who is knowledgeable, professional, and truly cares about her clients, Peggie is the one. We are so grateful for her help and would absolutely recommend her to anyone buying or selling a home!
