We have recently moved to Doha from SA and both my girls go to Montessori which is now Doha British School. I dont know how old your son is but we struggled to find place in any school for my 9yr old. The waiting lists here are crazy here for primary school. Maria Wild is the person to contact at the school and calling her is also a good idea. My girls are both happpy there and would love some more South Africans :)
