Greetings and welcome to fifth grade with Mr. Milburn.  I began teaching grades first through third in small-town Wisconsin and Minnesota nearly twenty years ago.  My first stop overseas was at the Singapore American School followed by eleven years at the Lincoln School in Buenos Aires, Argentina, and the past two years in Kathmandu, Nepal.  I’m thrilled to be at OSC teaching grade five. I enjoy being close to nature swimming, biking, and running.  Music is important to me, and I love to read. I look forward to a home with a garden and dog.

Hi! My name is Tassy Dahlan. I warmly welcome you and your child to Grade 5. I hail from Colombo, Sri Lanka but have lived the major part of my life overseas. This is my ninth year working at OSC. I am a Primary trained teacher who, after 20 years of living in Africa, relocated to Sri Lanka in 2009. I am passionate about travelling to and exploring different destinations, learning about various cultures and traditions and helping others in any small way. I am enjoying living back here with my family and friends. I am the mother of two wonderful sons and have the cutest grandson, ever!

Hey! I’m Sandamini Jayasinghe, the Assistant Teacher for Grade 5. I’m an OSC Graduate and thrilled to be teaching in my alma mater. I joined OSC in Preschool and graduated in 2008. I have completed my Bachelors in Education. Previously, I worked in the Primary Years Program at the British School and treasured working with young learners. I enjoy baking with my mother during my free time and we run a bakery called Ice & Easy Cakes.
