I don't train there, but am very familiar with the people.
Joe Soliz is very respected in Houston, he used to teach at Elite MMA (the largest MMA school in Houston). He is an old-school true martial artist in the best sense of the word. His specialty is JKD, but he is also a legit BJJ blackbelt.
His son Jason is a fantastic brown belt in his early twenties, one of the most successful and dynamic competitors in Texas.
Chad Kight is a brown belt under Royce Gracie and also a well-rounded martial artist.
Sugar Land MMA launched less than a year ago and is already putting together a very good team. Many of their students came over from other schools because the instructors were already highly thought of. They seem to have a good blend of hobbyists and serious competitors. Overall, a top-notch place to train.
