Who is the 

Nutritional Genomics Institute?​

CONTACT US

I had always struggled with multiple health issues from early childhood and found life in general, very challenging. When I was 11 years old, I was diagnosed with mononucleosis and missed 3 months of school. When I was 16, I developed an eating disorder and found solace in a hair pulling disorder. Whenever I was vaccinated, my body would ache from head to toe. My frequent childhood stomachaches were dismissed as “ a nervous stomach”. My lifetime of undiagnosed depression and anxiety was masked by competitive sports and rigorous academic achievements. My half-empty glass was periodically filled with vacations, beautiful pieces of jewelry and a very kind, patient, loving and positive husband. At age 40, my body was wracked with pain and I had countless food sensitivities. Conventional

medicine did not provide me with a viable solution since my body had a negative reaction to most medications. I always prayed that God would heal me. He did. Not overnight. Forty-five years later.


Six months ago, I had my first appointment with Dr. Chrissie Williamson, a

biochemist, Doctor of Clinical Nutrition, owner and CEO of the Nutritional Genomics Institute (NGI). Her practice is unique, effective, and personal. “Biochemical Individuality” is her modus operandi. Dr. Williamson is a non-pareil clinician. She blends functional testing with genetics and nutrition. Her knowledge and expertise in biochemistry

and nutrigenomics is unrivaled. Her wisdom and ability to discern and determine the nutritional genomic solution for ALL my health issues is truly unprecedented and has been life changing.

Today, I wake up happy and pain-free; I feel joy and I delight in every new day. Being on top of the world is an entirely new experience. 

Thank, you Dr. Williamson, for making my wellness a reality.

Miracles really do happen!

The Future of Personalized Medical Nutrition

Dr. Christy Williamson earned her DCN (summa cum laude) from MUIH, her master's degree (summa cum laude) in human nutrition from the University of Bridgeport and is a also a Certified Nutritional Specialist. Christy was active in the 2016 Virginia General Assembly in the passage of legislation which established a statutory definition of nutritional genomics. With a colleague, Christy developed a course in nutritional genomics for Maryland University of Integrative Health and continues to teach there as an adjunct faculty member.

Christy is the owner of the Nutritional Genomics Institute, OmicsDx, ZebraDx and SNPed. Personalized Nutrition was once considered the science of the future. Concepts such as testing metabolites (Metabolomics) and checking interactions between prescription drugs and genetics for potential adverse effects (Pharmacogenetics) can now be part of everyday care. NGI was born out of Christy’s desire to bridge the gap between "alternative" and modern medicine. This bridge is called integrative or functional/systems medicine. NGI also houses SNPed, practitioner education in nutritional genomics and ZebraDx, a Nutritional Genomics focused research diagnostics company. OmicsDx is software startup and state of the art nutritional genomics analysis company that produces epigenetically validated genome panels.

Michelle's Specialties

Michelle holds a Masters degree in Clinical Nutrition from the University of Bridgeport and is certified as a CNS by the Board of Nutrition Specialists. She also has training through the Institute for Functional Medicine (IFM). She is a former CPA who uses her research, spreadsheets and data gathering skills to use labs, functional medicine testing, a clients history and genomics to create personalized nutrition plans for a wide variety of conditions. Michelle started in-depth training with SNPed (Nutrigenomic training for practitioners) over two years ago and has whole-heartedly implemented nutrigenomics into the way she practices. She feels this is the missing piece for a lot of people and that this information can finally help them pick the right diet and truly understand how diet and lifestyle affect all aspects of their health. She enjoys helping individuals find ways to reach their wellness potential and understand "why they are the way they are."
