Marks Chowning joins Martha Turner Sotheby's International Realty this year pairing his extensive knowledge of the Galveston market with their world class real estate brokerage.


Drawn by the lure of the sea, Marks and his family relocated to Galveston in mid-2015 and now call the beautiful Texas gulf coast home. As a resident and professional in this coastal region, he is intimately familiar with the unique issues related to coastal living, specifically coastal insurance issues (flood, wind), differing building codes and construction requirements. Marks brings a wealth of experience in home renovation, commercial construction, and historic restoration, valuable knowledge given the amount of older homes and historic buildings on the island.


Clients praise Marks for his positive approach, decisive yet creative disposition, exceptional negotiating skills, and unwavering commitment throughout the entire transaction. He strives to deliver service that surpasses expectations, fostering "win-win" transactions, and addressing all of his clients' real estate requirements.


Marks started his career managing a variety of large public assembly, multi-use and commercial properties in markets across the United States. After 25 years of operating commercial properties, 2012 found him jumping into the world of residential real estate, launching his practice in Las Vegas, Nevada. As you can imagine, real estate, like everything else in Las Vegas, was dynamic and always moving, and he quickly became a top producer within his brokerage.


When Marks is not immersed in the world of real estate, he enjoys playing golf on the island's golf courses, nurturing vibrant tropical plants and relishing the freshest local seafood. Simple pleasures include exploring the island on his golf cart, sunset gatherings with friends and quiet time on his porch enjoying the breeze off the water.
