Samuel Zeiler, MS CNC

Sam Zeiler is the Director of the Robust Life Center in Seattle. He has a thriving practice with over 25 years of experience helping thousands of individuals achieve vibrant health.

He earned his Master’s Degree in Clinical Nutrition and Counseling from Donsbach University in 1982 with a BS in Nutrition. While seeking improved techniques and systems, he discovered Nutrition Response Testing®.  He enrolled and graduated as an Advanced Clinical Training Master in December 2008.

“Our physical bodies are made of basic elements in nature that promote the growth and survival of living things. The need for proper nutrition is of paramount importance in serving the body to restore full function with the ability to thrive. Nutrition Response Testing provides the most accurate way to define the specific nutrition that the body requires in a priority manner to maximize restorative power. It has been my joyful obligation to interest and instruct many practitioners in this work who now use the same techniques to successfully help their patients.”
