All Bodies Are Good Bodies
Our philosophy at Iris is that it’s never just about food. As a weight-inclusive Healthy-At-Every-Size (HAES) practice, we provide personalized nutrition counseling that explores the connection between emotions, habits, and health, offering practical plans and insightful care tailored to your life.
Whether you’re seeking support with body image, navigating chronic health concerns, or working to break free from rigid food rules, we help you embrace a sustainable, compassionate approach to eating.

Our Story
Allison Nutrition Consulting is under new ownership and is now Iris Nutrition Group. After joyfully serving Nashville for more than 35 years, Nan Allison retired from the practice in April 2025.
For the past three years, she has poured her wisdom, experience, and heart into mentoring the new owners, Cathey Stoner and Jessica Vancleave, preparing us to continue the work she began in 1988.
Our commitment remains the same: to provide thoughtful nutrition, rooted in understanding, and to offer nutrition care that sees the whole you. We believe that whole health starts with whole care—care that integrates the science of medical nutrition therapy with the art of listening, compassion and respect for your unique story.
Jessica is a Certified Intuitive Eating Counselor who specializes in helping clients overcome disordered eating patterns with kindness and inclusion.
Cathey is certified in Integrative and Functional Nutrition, offering deep expertise in women’s health, gut health, pediatric nutrition, and family-focused wellness.
The heart of Allison Nutrition Consulting remains the same—but we are evolving with care, growing as trusted voices in a wellness-focused culture, and staying grounded in the values that have guided this practice for decades.
The Meaning behind the Name
As we step into this new season, our new name reflects our core values and vision. The Iris, Tennessee’s state flower, inspires us—a symbol of resilience, growth, and strength. It represents the way we hope to walk alongside our clients and community.
Why We Rebranded
Our new name highlights our expansion into a diverse team of dietitians delivering a full range of nutrition care.
