Just Be Well: A Book for Seekers of Vibrant Health

Thomas A. Sult, MD


Millions of Americans suffer from chronic diseases—cancer, diabetes, depression, obesity, mental illness, and many more—and traditional medicine is failing to bring them back to health. Doctors write prescriptions to combat symptoms but, all too often, don’t even try to solve the root cause of the condition.

In Just Be Well, Dr. Tom Sult points the way toward a new path. He and a growing number of physicians practice functional medicine, a discipline that treats people, not diseases. Functional medicine doctors ask “Why do you have this illness?”—not “How can we stem the tide of symptoms?” They see that each of us is a marvelously interconnected system, and that when we understand what lies at the heart of a condition, we can work our way back to true wellness through changes in our lifestyle, attitude, and relationship with the world around us.

Chapter by chapter, Dr. Sult takes you through the eight key physiological processes of the functional medicine matrix, weaving together accessible information, real-life patient stories, and actionable advice you can use to begin your own journey back to wellness.

Whether you’re suffering from a debilitating condition or just don’t feel the vibrant health you used to, Dr. Sult’s advice will benefit you. The stories he has to share aren’t about miracle cures or instant results; they’re about how people just like you have joined the functional medicine movement and discovered the power to just be well.

Author Information


Tom Sult is a medical doctor, medical educator, author, and inspirational speaker. Despite all of this education, Tom’s early schooling did not go smoothly. By third grade, he was held back and diagnosed with “Minimal Brain Dysfunction,” now known as dyslexia. By the end of his second year of third grade, he had been bullied and teased and in school fights nearly every day. It wasn’t until the following year that, thanks to a mentor, Tom started understanding that a learning disability (something he now sees as a learning advantage) didn’t mean he was stupid.

In high school, another important mentor introduced Tom to the wilderness. He began rock-, snow-, and ice climbing, mountaineering, white water rafting, kayaking, and sailing, and eventually became a guide, calling the mountains his cathedral. Later, Tom supplemented his guiding income with a seven-year stint as a paramedic in emergency rooms and ambulances.

After being rejected from over forty US medical schools (because his grades, due to dyslexia, didn’t reflect his knowledge), Tom spent a year in acupuncture school and was then accepted at St. George’s University School of Medicine in Grenada, WI. There, he not only attended medical school but also followed and learned from local healers of the “bush doctor” shaman tradition. This experience fit closely with the Eastern traditions he was exposed to in acupuncture school.

After two years in Grenada, Tom transferred to medical school at UCLA, where he was invited to the home of Norman Cousins, a writer and the head of the psychoneuroimmunology department. Over the next two years, Tom spent as much time as possible at the office of psychoneuroimmunology, as he saw it as the scientific embodiment of the Eastern and shamanistic traditions he had experienced in acupuncture school and in Grenada.

The word doctor means teacher. To Tom, that is the most important definition of what a physician should be. Tom was recognized as the Resident Teacher of the Year as a resident in family medicine and is board-certified in family medicine and integrative holistic medicine. He is on faculty with the Institute for Functional Medicine, where he has taught hundreds of medical professionals of all disciplines the art of functional medicine. Tom is a contributing author to The Textbook of Functional Medicine and other publications and maintains a private practice in St. Cloud, MN. Just Be Well is his first book about functional medicine for the non-medical public.
