About Us:

Our preschool program strives to provide developmentally appropriate learning opportunities in a fun, effective, and safe environment. We focus on various domains of child development, carefully plan goals and objectives for each student, and work as a team to support individual’s learning.


We understand that each student comes from different background and life experiences. We value their unique differences and apply them to build meaningful learning opportunities.


We believe that parent/family involvement in early childhood education can extend student’s learning and make positive impact on their growth. We humbly appreciate parents keeping our communication lines open and flexible throughout the school year.
