About Mark Castleberry

Real estate is my second career — but helping people has always been my first.

For over 30 years, I led teams at major companies, guiding complex technology projects to success. I learned that real results come from clearly defining the goals, then building a plan that brings together the right people, processes, and tools. I built a reputation as a leader who delivered exceptional outcomes while taking great care of my clients — and that same mindset drives me today in real estate.

Now, I help people navigate one of life’s biggest decisions: buying or selling a home. It’s not just a transaction — it’s a turning point. I’m especially passionate about working with first-time buyers. In today’s market, homeownership can feel out of reach, especially for younger generations. Taking that first step is harder than ever — unless you have the right team behind you.

That's one of the reasons that I host a podcast called Sweet Home Texoma. Each episode dives into real-world strategies, expert insights, and practical advice to help you move forward with confidence. I sit down with mortgage pros, closing officers, insurance experts, home inspectors and others—so you get the full picture, not just the highlight reel. You can find it here: @SweetHomeTexoma.

Whether you're dreaming of your first home or planning your next move, I’m here to guide you with clarity, compassion, and a strategy that works for YOU. At Ebby Halliday, we are here to make home buying and selling a smooth and easy process for you.
