Headshot of Joe Duffy

Joe Duffy

Agent
REALTOR
License Number: 380588

With over a decade of experience in real estate—and a lifetime dedicated to serving others—I bring integrity, dedication, and heart to every transaction. I began my real estate career in Port St. Lucie, where I built a strong foundation helping buyers and sellers navigate the fast-moving South Florida market. In 2024, I relocated to Kingsport TN, where I’m proud to continue serving clients with the same passion and commitment.

Before focusing fully on real estate, I had the honor of serving as a professional firefighter and paramedic with Martin County Fire Rescue for 25 years. My career in fire rescue shaped who I am—teaching me how to stay calm under pressure, communicate clearly, and show up for people during some of the most important moments of their lives. Helping others isn’t just what I do—it’s who I am.

As a Realtor®, I believe buying or selling a home is more than just a transaction—it’s a major life milestone. I treat every client like family, making sure you feel informed, supported, and confident every step of the way. My goal is to build lasting relationships based on trust, hard work, and genuine care.

When I’m not working with clients, I enjoy spending time with my wife and our two sons. I love being outdoors, watching sports, and traveling—especially when it means creating memories with my family.

Whether you’re buying your first home, upgrading, downsizing, or relocating, I’m here to provide guidance with professionalism, integrity, and a client-first approach.
