About Donna Sadler

Donna Sadler lives in the Sierra foothills, home of the big pines and cedars of Volcano, California. She loves and enjoys hiking, bicycling (especially in Yosemite),organic gardening, and spending time with her family.

Donna has always wanted to be a teacher since a very young age. Finally, after many years, her dream has come true. She is now a teacher of nutrition and is a Holistic Nutrition Coach. The reason she started studying nutrition was first for herself because she wanted to be healthy and walking upright (physically well) at 100 years old. Second, she wanted to help her family and friends with their health concerns. And now her passion has evolved into wanting to help her community and the world learn how to improve their lives through optimal nutrition.

Donna’s desire is to share her knowledge of how nutrient-rich organic foods can nourish, renew, and heal the body and mind from the inside out. Optimal nutrition is her path to health and vitality and maybe yours too.

She wishes you a healthy-happy life!
