A patient I've been working with just had their PET SCAN come back clear after several months of discontinuing chemo and doing this work to heal.
Thank you for all the continued lessons and encouragement you provide. You are an amazing soul! Please thank Aria for all the good work she provides as well!
Paul is a trailblazer in the Root Cause movement, and his insights into the true causes of cancer are groundbreaking.
I can personally attest to the validity of his teachings, as I successfully healed from stage 4 testicular cancer by addressing the root cause.

Can I take your courses if I have cancer?
Will I be learning about GNM?
No. We do not teach GNM.
Pauls approach has developed from over 15 years of resarch into the lives of individuals with cancer, helping them identify and resolve significant stress, suppresed emotions, and create a life that truly noursishes them.
Much of what Paul has discoverd is contradictory to GNM. Our courses contain original material based on our own research.
