Bastyr Alum Authors Functional Medicine Book

Tom Malterre, MS, CN authors "The Elimination Diet"

Tom Malterre, MS, CN first heard of Bastyr from a community member in his hometown of Bellingham, WA. Always a lover of the outdoors, nature, diet and lifestyle, Bastyr’s location and Master’s in Nutrition program were a perfect fit for him.

And it was at Bastyr that Tom’s interest in functional medicine was sparked. Being in the presence of Bastyr’s founders Joe Pizzorno, ND, Bill Mitchell, ND, and Les Griffith, ND, along with Dr. Jonathan Wright and Jeff Bland inspired Tom to focus on Functional Medicine* as a profession.

After graduation, Tom went on to become a Certified Functional Medicine practitioner and is now an active educator, providing training around Functional Medicine and treatment of diseases and disorders including Alzheimer’s. Tom and his wife, Alissa Segersten (also a Bastyr alumna), together have launched the website,, and authored several nutrition/cooking books. They also developed the elimination diet, which is a tool that functional medicine practitioners use to help patients identify which foods are contributing to their health and well-being. It is also the title of their most recent book, The Elimination Diet.

According to Tom, “nothing would have happened without Bastyr.” As a student, he relished the holistic, multidisciplinary environment - Naturopathic Doctors, Psychologists, Herbalists - forming relationships that he cherishes to this day. Tom is most proud of the opportunity to carry the message delivered by Bastyr’s founders, giants in the natural health field. He’s especially honored to carry the torch when considering the uphill battle they faced in bringing naturopathic protocols to patients and students.

Tom met his wife, Alissa, at Bastyr and they are now parents to five children. He continues to be a lover of nature and encourages us to get back to the roots of naturopathic medicine: clean air, water, sunshine and exercise; the roots of life! He’s an advocate of preserving these roots, because without them we can’t have good health.

For Tom, Bastyr is leading the movement. And inspired by Bastyr, Tom is working to lead a movement as well. His next goal is to strengthen his online presence and offer more webbased live presentations.


*What is Functional Medicine?
Functional medicine is a systems-oriented clinical model for assessment, treatment, and prevention of chronic disease that incorporates the latest in genetic science, systems biology, and understanding of how environmental and lifestyle factors influence the emergence and progression of disease. Like naturopathic medicine, functional medicine looks at the whole person and is designed to empower patients and practitioners to achieve the highest expression of health by working in collaboration to address the underlying cause of disease.
