The Nutrition Improvement Center is a nutrition practice that focuses on helping you heal from disordered eating

Whether you or your loved ones need meal coaching, nutrition counseling, or group support
– we are here for you.

Seeking nutrition counseling and support for eating disorder recovery is a brave and important step towards healing your relationship with food and your body.

At the Nutrition Improvement Center, our team of Registered Dietitians provides personalized nutrition counseling and support to help you make peace with food, honor your body’s needs, and achieve long-term recovery.

When faced with trying to navigate the conflicting and confusing nutrition information online and relying on restrictive diets or meal plans, it can be overwhelming and discouraging to know where to turn for reliable and compassionate support.

The internet maze of harmful diet culture messages can be frustrating for those in eating disorder recovery, as it can feel like you are constantly bombarded with harmful messages that go against your recovery goals.

And if you’re someone in need of nutrition counseling and support, vetting practitioners to find those that prioritize a non-diet, non-judgmental approach to care can be overwhelming and time-consuming.
