Kelly Parcell, ND

I have always been interested in health and as a child I wanted to be a teacher. One of my favorite naturopathic principles is 'Docere' (doctor as teacher) which I practice every day with patients. 

I grew up in an athletic family where my mother had been the youngest star of the Canadian national ski team, and my father along with his own racing career was the Canadian ski team coach. Of course, I grew up in ski racing, which earned me a scholarship to college. After earning a Bachelors degree in Kinesiology (Exercise Physiology) from the University of Colorado at Boulder in 1990, I spent 6 years chasing finish lines as a Cat II road bike racer. I finally realized I would not be a professional athlete for the rest of my life and needed to move on. 

I was raised on brown bread and carrot sticks, which I was always so frustrated about. I wanted junk food! In hindsight, it shaped me, and it all made sense when I discovered naturopathic medical school. I completed my doctorate in naturopathic medicine from Bastyr University in Seattle in 2000.
