Welcome to
Jillian Greaves Functional Nutrition and Wellness
A place for women seeking supportive, personalized solutions for their hormone and digestive symptoms.
It's our mission to empower women to take back control of their health, to eliminate their symptoms naturally, and to experience life at its fullest potential.
Our Approach
Food is one of our most powerful tools in the prevention and management of disease. We also live in a culture where different diets and products are being marketed to us every day, along with conflicting nutrition messages that make deciding what to eat stressful and confusing.
As Functional Medicine Dietitians and Women's Health Specialists, we help women identify and address the root causes of their hormonal and digestive symptoms using advanced lab testing, personalized nutrition and supportive lifestyle therapies as the first line of intervention.
We’re best known for our whole-health approach and our ability to support and empower women in eliminating their hormone and digestive health symptoms naturally...WITHOUT restrictive diets, my fitness pal logging, or missing out on foods that you love.
We practice functional medicine nutrition and utilize cutting-edge research to provide exceptional care to women in an environment that is always supportive and empathetic.
From chronic low energy to debilitating digestive and skin issues to horrible PMS and irregular cycles, we know firsthand what it's like to have your symptoms dismissed by providers and to be told that everything is fine or to "just take birth control."
After years of education and advanced training, healing our own bodies, and working with over 1000 women in our programs to transform their health, we know what works.
Here's How We'll Do It
Here's How We'll Do It

Health is rarely ever black-and-white and we know the rigid + restrictive diets don’t work. Work with us to find flexibility and to establish sustainability as we find the right balance to support and nourish your body from all angles.
Remove the guilt and ditch the extremes of diet culture messaging to achieve whole body health and establish a personalized pattern of eating that allows you to fully engage in life while also achieving optimal health.
03/ Align your whole self - body and mind.
