About Us


As a Nutritionist and Health Educator, I have devoted my life to teaching people how to achieve optimal health and longevity through a healthy plant-based vegetarian diet. A whole food, plant-based diet (ideally a vegetarian diet), rich in fruits, vegetables and other healthy plant foods is powerful medicine in preventing, effectively treating and even reversing many of the diseases we face today. This diet, plus regular exercise, healthy lifestyle habits, and a positive mental attitude will lead to optimal health. I believe it is possible for each of us to enjoy total wellness for the body, mind and spirit.

“…I pray that you may prosper in all things and be in health, just as your soul prospers.”
