There are a lot of good preschools in Doha. At the bottom right hand side of your screen is a Guide to Qatar. click on the Qatar schools database and go from there. also the Marhaba book that you can buy at Jarir bookstore & all grocery stores have a great list as well. I would take into account where you live (you will not want to drive across town in doha traffic if you can help it!) and your budget. Good luck
