International Schools in Colombo

Hi, my family and I will be relocating later this year and need to find a school for our 3 & 5 year old children. There seem to be several international schools and I am wondering if anyone has any recommendations? The school in Battaramulla seems a bit far as we will probably be living in the city near my husbands work place. We are an American family and are looking for a school that would provide an education similar to what the children would receive if they attended private school in the US. Thank you in advance for any comments and advice!
