Our Staff

​At the Institute of Eating Management, we have a variety of licensed professionals for you to see. Keith is licensed as a Certified Clinical Nutritionist (CCN), Kim is licensed as a Certified Nutritionist (CN), and Heather is licensed as a Registered Dietitian (RD).

The different license variations represent the fact that our staff has had extensive academic training in nutrition, clinical nutrition, nutrition counseling, biology, chemistry, and anatomy/physiology, just to name a few.  The variations also represent the fact that our staff has had extensive “hands-on” training in several different nutrition-related settings.

No matter which IEM staff member you work with, you can be sure you will get the most from both our various levels of education and our vast experience.
