Anyone have a successful career in holistic medicine/nutrition?

I'm wondering if a career in this field is legitimate and possible. I am passionate about living this way, so having a career in this field would be a reflection on how I live. I have found some on line schools that offer degrees in Holistic Health, but I wonder if that will get me anywhere or would I need a degree or additional schooling elsewhere? I would like to work in a doctors office of some type, I'm considering Holistic Nutrition or Practitioner. Do these jobs even exist? Advice from someone who is successful in this field would be helpful.
