Lakshmi Ranatunga
Kindergarten teacher
Associated Montessori International Diploma (AMI Diploma)
Units in development in early childhood education from the University of California Los Angeles (UCLA)

My name is Lakshmi Rantunga. A Sri-Lankan national, having completed my early education in Sri-Lanka and in Nigeria in West Africa, I was attracted to the Early Childhood teaching profession. With over 25 years of teaching experience which has taken me to several different parts of the world, I currently work as a kindergarten teacher at ISKR. Kindergarten is an exciting time in a child’s life. They bouncing with energy, curious, ready to explore and eager to learn all you can offer.
I find it extremely rewarding to support and guide the children along this new and exciting path of learning and help them make that transition to 1st Grade! ISKR is a great place to be.
