Cheryl Atkinson
Brookline, MA - Feb 24, 2026

Kate Duggan is amazing. We were so glad to have had Kate by our side as we sold our condo and bought our new home in Brookline. When we hit an unexpected setback with our first buyer and had to walk away from the deal, it could have been incredibly stressful. But Kate stayed calm, positive, and completely focused. She didn’t miss a beat — quickly finding us a new buyer and guiding us through every step with reassurance and confidence. She truly went above and beyond. From coordinating documents with the condo management to helping us navigate a few minor repairs, she handled countless details behind the scenes that made everything feel seamless on our end. When it came to finding our new home, Kate really listened. She understood what mattered most to us and helped us find the perfect property. We always felt heard, supported, and genuinely cared for throughout the entire process. Selling and buying at the same time can be overwhelming, but with Kate it felt manageable We are so gratef
