    Our Books

  • In Please Bless the Refreshments, Dr. Bradford and Dr. Sexton explore the connection between faith, religion, and healthy living.  Healthy living is more than just what you put in your mouth to eat.  There are multiple components to help one achieve optimal health.

    Dr. Bradford and Dr. Sexton dive into an essential, but rarely discussed, topic.  Cultural heritage, social milieu and religious community are all basic factors that create the patterns that we live by: even sleep cycles, activity patterns and what we eat.  Focusing mostly on the latter, the authors look at a background of contemporary American upbringing in a culture that celebrates the nutritional impoverishment of the Standard American Diet.  They step back and examine culturally reinforced patterns of eating.  This the first step in making better choices.  As naturopathic physicians, these two doctors are by training among the best qualified to lead the way forward toward more informed choices of high quality foods.


    Manifesto for a Cancer Patient

    What choices do cancer patients have?  Why do those choices seem so few?  This book is a manifesto for patient rights and a manual through the cancer journey, from a doctor’s perspective.  A newly diagnosed cancer patient is told:  “There is nothing else that works against your cancer except chemotherapy and radiation.  So you are going to start chemo now.”

    It doesn’t have to be this way.  Completely different treatments for cancer exist and are discussed in this book.

    Cancer patients who choose naturopathic treatments over chemotherapy are berated by those who had already decided on a treatment plan.  Naturopathic physicians treat cancer patients, and are criticized by paradigm doctors.  Is the war against cancer, or against alternatives to the status quo?


    Choose Your Foods Like Your Life Depends On Them

    Examine the relationship between the foods you eat and the symptoms you manifest.  We eat our way into our symptoms, and we can eat our way back out.

    This book offers a challenge along with redemption:  Forget everything you ate until today, and start over.  The choice is between a set of foods that will nourish you and enhance your longevity on the one hand, and the foods that tear you down subtly and gradually on the other.  More importantly, that choice is always in front of you.  You can turn around bad habits, bad choices and the resulting bad symptoms at any time.  Here are some strategies to get started.  Do it now, because you’re better off preserving the health you have than letting it deteriorate.
