Welcome to a practice where nutrition meets purpose, culture, and a whole lot of love! Rene and Chelsea Marquez are the husband-and-wife team behind this mission-driven private practice—combining clinical expertise, cultural passion, and a shared vision for helping others thrive. JTA (Jan Tilley and Associates) Wellness was founded by a trailblazing dietitian whose passion for nutrition and community laid a strong foundation for what the practice is today. As the new owners, Rene and Chelsea Marquez chose to keep the name JTA Wellness as a tribute to that legacy—honoring the impact she made in San Antonio and beyond.
