Cancer is the most elusive, cunning, adaptable, intelligent, and innovative disease in history, and it has been outsmarting us for a long time.

If you are landing on this page, you are a physician who is truly a student of science and interested in discovering how the integrative side of medicine can benefit your patients. On this page you will be able to learn about:

  • How we help to support patients going through a cancer journey
  • The resources we offer patients
  • Scientific research on Mistletoe Therapy and it’s benefits for patients
  • Informational webinars and training courses available to you as a physician

Our goal at Believe Big is to be a bridge for patients and doctors by providing helpful resources so each, unique cancer patient can find their best pathway to healing.


Believe Big is a non-profit Christian organization founded by Ivelisse and Jimmy Page after her battle with stage IV colon cancer without the use of chemotherapy and remains cancer free today. Since 2011, Believe Big has helped thousands of patients move through the overwhelming process of cancer by bridging the gap between conventional and complementary medicine. Believe Big not only helps patients survive but thrive. Not just physically, but emotionally and spiritually as well.
