What's My Home Worth?

Trish Duncan, Thornbury REALTOR® ... and beyond

Whether you’re buying or selling real estate, you need someone who understands people, moves fast, and delivers results. I don’t just sell houses – I help people write their next chapter. With 10 years of experience and 300+ successful transactions totaling over $175 million in sales, I’ve guided countless clients through every plot twist the market throws their way. My Psychology training and Family Mediation background give me an edge in negotiations that gets you the best deal, while my experience running a fast-paced roof repair company taught me that timing is everything — in real estate, it’s the difference between a happy ending and a missed opportunity. Combined with my absolute love and passion for this 4-season paradise, I’m ready to help you turn the page today!
