To that end, it offers sermons, bible study, youth ministry programs and worship in English and Chinese. The grounds also house a fully- licensed and accredited elementary school with capacity for 150 children as well as a pre-school with a capacity for 80. Tuition is reasonable and the school also offers sibling discounted rates. Enclosed and spacious outdoor playground is part of the facility.
