Allison Nutrition Consulting is a Nashville-based nutrition practice with nearly 40 years of compassionate, expert care behind it. Founded by Nan Allison, MS, RDN, LDN—a true pioneer in the world of nutrition therapy and an early champion of treating the whole person—our practice is built on the belief that everyone has the potential to develop a peaceful, intuitive relationship with food and their body. That belief continues to guide everything we do.

Today, the practice is led by registered dietitians Cathey Stoner, MS, RDN, LDN and Jessica Vancleave, MPH, RDN, LDN who have worked closely with Nan, managing the day-to-day operations, while being guided by her leadership and vision. Jessica is a Certified Intuitive Eating Counselor who brings a gentle, inclusive approach to helping clients rebuild trust with food and body. Cathey is certified in Integrative and Functional Nutrition and is especially passionate about supporting women’s health, gut health, and working with kids and families. Together, they’re committed to creating a welcoming space where your whole story matters.

At Allison Nutrition Consulting, our approach combines solid, evidence-based medical nutrition therapy with the kind of care that comes from truly listening. We offer one-on-one sessions, coaching, and practical tools—like meal planning, food exposure work, grocery support, and real-world education—that help create lasting, sustainable change.
