Services
Preschool
Our preschool program offers play-based learning with small class sizes and low student-teacher ratios. Children develop social-emotional skills through cooperative play while preparing for kindergarten through creative activities. The curriculum emphasizes hands-on exploration in math, science, and literacy through age-appropriate learning centers.
Forest School
This outdoor-focused program combines play-based learning with weekly nature field trips to San Diego's parks and preserves. Children engage in physical development through climbing and exploration while learning environmental awareness. The curriculum integrates early math and literacy through nature-based projects and sensory experiences.
Transitional Kindergarten
Designed for 4-5 year-olds, this program bridges preschool and kindergarten with focus on emotional readiness and academic foundations. Students develop fine motor skills through scissor use and letter formation while building social competence through peer interactions. The emergent curriculum adapts to children's interests through project-based learning.
Infant Care
Our infant program provides nurturing care with a 3:1 student-teacher ratio, focusing on sensory development and early communication. Caregivers implement consistent routines for feeding and sleeping while encouraging motor skill development through tummy time and interactive play in a secure, stimulating environment.
Toddler Care
This program supports toddlers' growing independence with a 4:1 student-teacher ratio. Activities promote language development through songs and stories while fostering social skills during group play. Teachers guide emotional regulation through positive discipline and encourage self-help skills during daily routines.
