Bethany Linnenkohl Lafferty

Owner, Practitioner Consultant, ACN

As a second-generation Standard Process representative, Bethany Linnenkohl Lafferty has immersed herself in the whole food philosophy and the age-old truths of Dr. Royal Lee. Bethany is passionate about health and wellness and, as an entrepreneur, she founded two food-related businesses and lectured as an advocate for raw foods during her college years. After completing an undergraduate degree at Biola University, she continued post-graduate studies at the University of Washington in Business Administration and later, Applied Clinical Nutrition. Although my time at Standard Process has come to an end, the next chapter has begun offering whole food nutrition through Doctors’ Research Supplements.

Our Values

We value Healthcare Practitioners and education.

We form relationships built on trust and integrity.

We believe food supplements should be made from food.

We are committed to Royal Lee’s Philosophy, including that Patient care should be offered via nutritional advice from a Healthcare Practitioner.

We only carry products we use ourselves and recommend to our family and friends.
