Hi everyone, I am Mr. Keith. I am very delighted to join the family of LA.

I was born and raised in HK and got my bachelor degree of science in Mathematics. This is my pleasure to teach Mathematics at LA. I enjoy solving problems with students together. I like to know the way they think and share with them my knowledge. Sometimes it’s really so joyful to see them using creative and smart methods to deal with the problems. I wish we can learn and grow together.
