WELCOME TO Texas Advanced Surgical and Bariatrics
Joel A. Rodriguez, M.D., F.A.C.S. established Texas Advanced Surgical and Bariatrics for the advanced surgical treatment of overweight and obesity. Dr. Rodriguez specializes in weight loss surgery, including laparoscopic gastric bypass, sleeve gastrectomy, duodenal switch, gastric band, and revision surgeries (revision of previous bariatric procedures).

Providing this level of comprehensive care allows us to match therapy specifically to a patient’s needs and goals.
Patience and Compassion: We will not rush you to make a decision. We will explain the risks and benefits thoroughly, in terms that you can easily understand. Our preoperative goal is that you walk out of our office feeling confident in the decision you have made.
Full Time Staff: The office staff at Texas Advanced Surgical and Bariatrics is dedicated to helping patients navigate through the insurance process. Our insurance specialists are experienced at navigating the challenges of insurance approval and will work diligently to get through the process quickly and efficiently.
Dedicated Patient Advocate: You will be assigned to a personal patient advocate who will be there to help as you go through the preoperative process. Your patient advocate is your direct link to Texas Advanced Surgical and Bariatrics.
Commitment to Your Long-Term Success: Our doctors understand the challenges that weight loss surgery patients face after surgery. They are passionate about being there for you every step of the way. We will provide high-quality care, with great attention to detail, so that your results are maximized.
