Hi. My name is Mark Diehl and I am a Realtor with Coldwell Banker and The Lisa Gregory Real Estate Group. Galveston Island is my home and I am so privileged to share my island with visitors and prospective buyers every week. Over the years, as my real estate career progressed, I sought to affiliate with a real estate firm that could provide the most value to my clients. I discovered that Coldwell Banker offered the most services and the best marketing technology, allowing my sellers the ability to enjoy a greater market reach to advertise their home or property.
