Nancy Mullan 


Some people call Dr. Nancy Mullan the MTHFR genetic medicine expert.


Dr. Mullan works with people who have the MTHFR mutation and the chronic health issues it can cause.  She uses diet and genetics based nutritional supplementation to help you increase energy, feel strong and vital, and to reconnect with love and joy.

Dr. Mullan has a passion for precision and getting it right. She says, “Pharmaceutical symptom removal is not a solution, although it can be useful. The underlying cause of the problem needs to be addressed.” She further states, “Chronically ill people are desperate for symptom resolution. Your lives are devastated by disease processes, some of which are life threatening. I want to offer you something better than mainstream solutions.” And she does this. Applying her understanding of Dr. Amy Yasko’s method, and carefully implementing the interventions suggested by biochemical testing, Dr. Mullan negotiates the labyrinth of chronic illness to finally get symptom resolution for you.

Dr. Mullan has studied at a number of exceptional institutions: the University of Pennsylvania, Tufts University School of Medicine, and the University of Chicago Hospitals and Clinics. She excels at integrating the results of biochemical and genetic testing into sustained clinical improvement for you. She has succeeded with patients who confounded the specialists at Massachusetts General Hospital, the Mayo Clinic, the Cleveland Clinic, Stanford, and many well-known integrative medical doctors. When recommending her, her patients say, “This is the woman you need to talk to. She really knows how to handle tough clinical problems.”

With deep and compassionate interest, Dr. Mullan relates to her patients with a candid and down-to-earth demeanor. She and Dr. Yasko have an impressive track record for getting you to the other side of very frightening and intractable illnesses. Both doctors are tremendously invested in clinical innovation and finding what it is that will get you well. Her specialty areas are MTHFR+, Methylation Genetics, and genetics based nutritional supplementation. Within this context, she most often works with Chronic Fatigue Syndrome, Psychiatric Disorders, Autism Spectrum Disorders, Gastrointestinal Disorder, and Heavy Metal Toxicity.
