If you are recently diagnosed with celiac, I generally advise people to start with the Celiac Crash Course which covers what would take over 12 sessions with a celiac dietitian for a fraction of the cost. Most students find the course is enough to help them heal and feel comfortable keeping themselves safe from gluten and cross-contact no matter where they find themselves.
Should you need more help or you are not recently diagnosed and need more intensive care, I see people 1:1 only in 6-month coaching commitments.
I find that the work I do with healing celiac, intuitive eating and body image is hard work and long lasting change with it requires consistent accountability and support.
Seeing people for 6-months helps make that happen.
