Designa a week detox program for a retreat & offer education to participants

We are starting a retreat in Andalusia (the south of Spain) in a natural park area. We need nutritionists/dietitians to 1. design week detox program, 2. accompany the clients during the week, help them redesign their nutrition habits and offer education to the participants to the program during the week. For this we are looking for candidates with experience in detox retreats. There will be several courses during the year and the candidate could join one or several depending on her/his preferences. Candidates should have a high level of English, Spanish is not a requirement
