Rachel's Story

"My work with nutrition has been shaped by my own experiences and the experiences of the people I love. Suffering with IBS and hypoglycemia in my youth, I was driven to find the underlying mechanisms causing my ill-health. I knew, deep down, that the answer was within my own physiology.  If I could figure out what was out of balance, I could change things. 
Every one of my specializations has developed from a desire to help someone in my life- client, friend or family member. To me, there is no greater honor than contributing to another’s wellbeing. "

What is Functional Nutrition?

Functional Nutrition is focused on building health by restoring proper physiological functioning of the body. Seemingly unrelated signs and symptoms give clues about the underlying cause of illness or disease. Instead of suppressing the symptoms with natural or pharmaceutical agents, I piece them together to get a picture of the root cause(s) and create a plan offering the appropriate support.

Together, we explore your personal story and look at diet, symptoms and physical signs, health history, lab work, lifestyle, activity, family and social life, toxin exposures, stress, sleep, etc. to develop an approach that is right for you. 

Are you a candidate for a Functional Nutrition session?  You may be if:

  • You have a health problem or risk factor, such as high blood pressure or high cholesterol.
  • Your doctor tell you that you can improve your condition with better nutrition.
  • Diabetes, cancer, heart disease, or osteoporosis run in your family.
  • You are overweight.
  • You have questions about what foods you should eat or whether you should take vitamins.
  • You think that you would benefit from seeing a registered dietitian or someone who specializes in nutrition counseling.
