Testimonials
I had a truly exceptional experience working with Tammy to sell my home in Waterford—especially during what turned out to be a challenging moment in the market. I met with three other realtors before choosing Tammy, and I never once second-guessed my decision. From start to finish, she made me feel supported, informed, and genuinely cared for. Tammy consistently went above and beyond—bringing fresh flowers for showings, adding thoughtful touches for the open house, and always showing up with warmth and professionalism. She’s not only personable and easy to work with, but also sharp, strategic, and deeply knowledgeable about the local market. I wholeheartedly recommend Tammy to anyone looking for a realtor they can truly trust, and I would gladly work with her again on either the buying or selling side of a future transaction. Thank you, Tammy! Willa Kammerer Willa Kammerer
