In the late 1960’s Dr. Marshall was unexpectedly guided to a career in the science of nutrition when he contraced a nearly fatal illness. After numerous attempts at medical treatment provided no help, he embarked upon a healing journey to find different answers.
Extensive research in nutrition and biochemistry provided the effective solutions he was so desperately looking for. Dr. Marshall then began using his discoveries to provide comprehensive nutritional counseling and lifestyle programs for those people wanting to experience and enjoy optimal health.
