Ashley Marquez, owner of GTX Realty Group and voted Best Real Estate Agent in Galveston County for 2024, has been immersed in real estate from an early age. Her grandfather was a real estate investor, and growing up around his stories, properties, and lessons shaped how she views real estate today. That early exposure helped her become not only a knowledgeable agent but a smart investor and landlord herself. As a Galveston local, Ashley knows the island inside and outfrom the best neighborhoods to invest in, to the hidden gems buyers fall in love with. She leads GTX Realty Groupa boutique team of dedicated professionals that, in its very first year, was voted Best Real Estate Company in Galveston County for 2024. It's an honor Ashley is incredibly proud of and a reflection of the care and commitment she brings to every client and every deal.Whether you're buying, selling, leasing, or investing, Ashley provides honest advice, sharp market knowledge, and creative marketing that gets results while making the whole process feel smooth and stress-free.She holds the ABR, PSA, RSPS, and SRS designations, and has been recognized with honors including Top Realtor by the Daily News (2021), 40 Under 40 (2020), and one of the top agents in Texas on social media (#45 in 2024). But more than anything, Ashley's proudest moments come from repeat clients, word-of-mouth referrals, and helping people find the perfect home in Galveston.When she's not out showing houses or supporting her team, you'll likely find her volunteering at the animal shelter, or fishing/being outdoors with her husband and fur babies.

“My husband and I found Ashley via Google and it was important to us to ... “My husband and I found Ashley via Google, and it was important to us to find a realtor based in Galveston, who knew the destination inside and out - as we were moving from another state to purchase a new primary residence on island. I called Ashley on a Sunday, expecting to leave a message, but instead she answered the phone and spent quite a bit of unhurried time asking us about what we were looking for in a house in Galveston. Throughout, she listened, gave great advice and when we met her in person a couple of weeks later the wonderful connection we’d established continued. She was professional, honest, organized, accessible, kind, thoughtful and made us feel through the entire process that we were her most important clients. I’m sure she makes everyone feel the same – which is what makes her amazing. She helped us find our dream house! We recommend her unreservedly." Read more
