About Melissa Dunn

Melissa Dunn, REALTOR® | Main Key Realty

Raised right here in Jefferson County, Melissa Dunn brings deep local knowledge, a strong business foundation, and more than 20 years of leadership and customer service experience to every real estate transaction.

Before becoming a REALTOR® and joining Main Key Realty, Melissa built a successful career with Walmart, where she worked her way into management. Throughout her career, she gained extensive experience leading teams, solving problems under pressure, staying organized, and ensuring customers received exceptional service. Those years taught Melissa the importance of communication, attention to detail, and results-driven leadership—skills that now make her a strong advocate for her real estate clients.

Melissa also holds a Bachelor’s Degree in Business from the University of Missouri–St. Louis (UMSL), combining her education with decades of hands-on management experience to provide her clients with knowledgeable, thoughtful guidance.

For Melissa, real estate is about much more than buying or selling a house. It’s about helping people move confidently into the next chapter of their lives. Whether she’s helping a first-time buyer find the perfect place to call home, assisting a family with selling a home they’ve loved for years, or helping a client explore an investment opportunity, Melissa takes the time to understand what truly matters to them.

From coordinating showings and negotiating offers to navigating inspections and walking clients through closing day, Melissa’s goal is simple: make the process as easy, informed, and stress-free as possible.

Known for her big heart, calm approach, and genuine care for others, Melissa goes above and beyond to make sure her clients feel heard, supported, and confident every step of the way.

When you work with Melissa, you’re not just getting a REALTOR®—you’re gaining a trusted local partner who treats your goals as if they were her own.
