My passion is to provide a unique, successful approach to health and wellness. This is accomplished by a personlized approach utilizing, Nutrigenomics,  Functional, and Homeopathic Medicine.  As a Chiropractor  I know the importance of nerve function in maintaining good health. Other important aspects of health are nutrition, eating habits, exercise, emotional health, and spirituality. Eighty percent of the health conditions we face today are from lifestyle choices.  


The genomic revolution has arrived.  It is helping move the focus of clinical practice toward improving assessment, treatment, and prevention of complex and chronic disease through a deeper understanding of each individuals unique combination of genetics, environment and lifestyle. The focus on the microbiome is one example.


As a Functional  Medicine practitioner, I focus on personalized healthcare to prevent and find the underlying causes of disease, not just symptoms.  I believe the entire "patient story" needs to be heard and understood in order to truly help the patient. I enjoy working with families to see the connection in inherited conditions. I have been practicing in  Concord, MA for 33 years.

​Dr. Williams offers testing, from CLIA certified lab facilities, to assess nutritional status, nutrigenomics, pharmacogenomic, digestive function,  allergies, gluten reactivity and Celiac Disease. Gluten sensitivity is 6x more prevalent than Celiac Disease.



Functional medicine reflects a systems biology approach which involves an analysis of how

all components of the human biological system interact functionally with the environment over time.

Functional medicine, in agreement with modern medicine, holds that the entire "patient story" needs

to be heard and understood in context in order to truly help the patient.

A Fresh New Perspective on Your Health

"My impression upon consulting Dr. Williams was that, for the first time, I was talking with someone who actually practices medicine. Her practice is to understand and treat causes, not just treat symptoms. For fifty years I have had moderate to severe gastric and related issues. It now appears that they were all caused by a combination of food allergies that went undiagnosed and the aftermath of pharmaceuticals. After three weeks I told my wife that I was just about at the stage of saying that I never knew that the way I now feel (pain and symptom free) is the way one is supposed to feel."
