Welcome!!! I am Donna Sierra and I will be handling TMD Class. :) 

I have a Bachelor's degree in Psychology and a Master's degree in Education major in Special Education. This is my 5th year teaching at JMS, but this year marks my 13th year teaching in total. I am married and I have a wonderful son. I came from the Philippines which is one of the countries in South East Asia. I love music and I love playing volleyball. My dream is to travel the world and explore more beautiful places.
