About Us

Hi! I’m Nina Milan. I created the Top Key Referral Network to bring together a trusted community of real estate professionals who truly care about people.

I’ve been in real estate since 2004, and I know this business takes more than just market knowledge — it takes heart, persistence, and the ability to really listen. I bring a tenacious work ethic, professional poise, and emotional intelligence to every relationship. My clients know I’m in constant communication, going above and beyond to make sure they feel supported every step of the way.

I fully embrace the tools and technology that give buyers and sellers an edge, while never losing sight of the human side of this process. With the full support of Coldwell Banker behind me, I combine marketing savvy, market insight, and genuine care to deliver results that simply can’t be matched.

Through the Top Key Referral Network, my goal is to share that same level of dedication by connecting families, buyers, sellers, and professionals with the people who will serve them best.

Connections That Fit

Three colleagues, two women and one man, are gathered around a desk with a laptop in a brightly lit modern office. They are engaged in a discussion, with one woman sitting and smiling at another woman who is sitting with one hand on her shoulder and a laptop in front of her.

Top Key Referral Network was created from a simple truth: too many clients end up frustrated with realtors they found by chance. Personalities often don’t align, communication breaks down, and clients feel stuck with the wrong fit during one of life’s biggest decisions.

That’s why Top Key exists — to connect clients with trusted, compatible real estate professionals who put people first. Our mission is to make sure every client feels confident, cared for, and in good hands.

Built on Trust, Focused on You

  • Client-Centered Service: We listen first, tailoring each experience to reflect the client’s unique goals and priorities.

  • Excellence: From first contact to closing, we deliver results that exceed expectations.

  • Collaboration: By working together, our network ensures clients always have the right professional by their side.

  • Compassion: We understand the emotions involved and provide reassurance when it matters most.

  • Commitment to Satisfaction: Your success is our success, and we don’t stop until you’re fully satisfied.

Trusted Agents, Proven Results
