Treehouse Languages specializes in fun foreign language materials for children, lessons are interactive, thru games, songs and activities; all the materials are developed age appropriate. We are located in Glendale, Arizona.

Rosalia Vallelonga started Treehouse Languages 4 years ago, teaching Spanish in a small Montessori school with only 14 children. She created her own materials, and curriculum, making changes, accommodating them to the way the children learn. She then started teaching after school programs at a few public schools.

Rosalia recently finished her Montessori training for preschool-Kindergarten from NAMC and is currently teaching Spanish at a private Montessori school.
