Listen to Lemberg parents

"Lemberg teachers and staff celebrate the many cultures and languages represented in their classrooms, sparking a child's natural curiosity and appreciation for diversity.

"My 4-year-old loves to listen to foreign languages, practice Lemberg's counting from 1 to 10 lessons in various languages, hear about foreign countries and meet people from countries outside the United States.

"Combined with the lessons we teach at home, Lemberg has provided such a great basis for valuing multiculturalism."
