The last couple weeks I have visited Columbia Asia. I did my health check there for my work permit. Yeah, I know I could have used Cho Ray Hospital but the service I am using chose Columbia Asia for convenience. One thing I will give Columbia Asia, it does have the feel of a small US medical clinic I am used to visiting. The staff are friendly and I like my doctor, Dr. Reeta.
I know several people that have used Columbia Asia and we are all happy.
