From a Single Vision to a
Legacy of Wellness and Beyond
The Beginning
From One Dietitian to a Full-Fledged Team
JTA Wellness began in 2006 as a one-person private practice founded by Jan Tilley, MS, RDN, LD. What started as a solo operation quickly gained traction, leading to a growing client base, a second dietitian, and a new office space. Over the years, she wrote Getting Your Second Wind, Healthy Meals for Hurried Families, and Eat Well to Be Well.
A New Chapter
Rene & Chelsea Marquez
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.
Our journey began with a shared love for wellness, culture, and faith—and a deep belief that food has the power to heal, connect, and transform.
Carrying Forward
Honoring the Legacy, Expanding the Vision
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.
Looking Ahead
Where We’re Headed
At JTA Wellness, we’re dreaming big—and building boldly. Our vision is to expand our reach across San Antonio, throughout Texas, and ultimately, around the globe. We believe that everyone deserves access to high-quality, culturally inclusive nutrition care, no matter where they live. That’s why we’re working to grow our locations and broaden our services to meet the diverse needs of our communities.
