Mt. Calvary Lutheran Preschool and Day Care is a faith-based, NLSA-accredited center at 23300 Golden Springs Dr in Diamond Bar, CA, serving children ages 2–5 with a developmentally appropriate Christian curriculum.

Programming integrates Saxon Math and phonics-based language arts with active learning, physical education, and music; a weekly Children's Chapel and Bible stories anchor the faith-focused approach.
