Health co-ops are generally found in rural or remote communities. You rarely have specialists there. You usually have general practitioners or other types of health professionals. If there aren't physiotherapists, nutritionists or general practitioners in the community, and if it takes 20 minutes, half an hour or 45 minutes to get to the nearest clinic or to get to another clinic, the people in the community are going to decide to invest in having these doctors closer to them.
