Our Story
Built on relationships not transactions
Broker-Led. Value-Driven. Personally Involved.
With over 23 years of experience and more than 3,500 transactions managed, I bring a valuation-first approach to real estate that most agents simply don’t have.
Before founding Iron Star Realty, I was a certified appraiser in multiple states and managed regional real estate appraisal groups across the DFW area. This background allows me to price homes accurately, negotiate from data, and advocate effectively for homeowners — whether selling, buying, or fighting unfair property tax assessments.
Iron Star Realty is intentionally broker-led, meaning every client works directly with me from strategy to closing.

Experience Built Over Decades
Real estate isn't just a job for me; it's a lifelong discipline. From growing up in a real estate family to managing complex appraisals, every step of my journey has prepared me to protect your interests today.
1985 — Foundation in Real Estate
Our family’s real estate roots began when my mother earned her real estate license, laying the foundation for decades of market knowledge, client service, and hands-on experience.
1995 — Early to Real Estate Exposure
From an early age, I worked behind the scenes assisting my mom’s real estate team — learning contracts, transactions, and the realities of client service long before becoming licensed myself.
2002 — Advanced Market Insight
During this period, I managed appraisal operations and teams, gaining experience in valuation at scale — a background that directly benefits buyers, sellers, and tax protest clients today.
2008 — Licensed Real Estate Agent
I obtained my real estate sales license and formally transitioned into sales, bringing valuation expertise, negotiation skills, and market analysis into every transaction.
2016 — Iron Star Realty Established
Iron Star Realty was formally established to reflect what had already been years in the making — an independent, client-first real estate business built on experience, transparency, and results.
Mary Ann Byrns — Founder Emeritus
My mother, Mary Ann Byrns, spent more than 40 years in North Texas real estate, and I had a front-row seat for much of it. She was always ahead of her time — one of the first agents to add “take one” tubes to her listing signs, and the proud owner of a car phone bolted to the floor with a pigtail cord and an antenna sticking out the back window. It was such a novelty that my friends would call their parents just to say they were calling from a car.
Some of my earliest memories are late nights at the office, when MLS listings arrived weekly in thick, phone-book-sized binders. Contracts were simple one-page forms with white, pink, and blue carbon copies that I usually ended up playing with while she worked. I spent weekends at open houses, especially new construction, exploring trails behind the homes and playing with clients’ kids.
Real estate didn’t take her away from me — it gave us time together in ways most kids don’t get to experience with their parents.
Throughout her career, Mom built her reputation on exceptional communication, strong negotiation skills, and genuine advocacy for her clients. She embraced education and evolving technology long before it became industry standard, always believing that knowledge is the foundation of great service. Over time, she chose to focus less on transaction volume and more on the relationships that mattered most.
Today, I work with the grandchildren of clients she helped decades ago — a testament to the legacy she built. Though retired from active brokerage, Mary Ann remains the heart behind Iron Star Realty’s values, and her influence continues to guide how we serve our clients today.
