In 1965 Hank and Millie Primanti opened Primanti Montessori School of Whittier, serving students ages 2 ½ years to 6 years old in Orange County and LA County. The school was a pioneering Montessori school and became well renowned. It was a legend. Its unique architecture is modeled after a Montessori school in Holland. It was the first school to build mirror rooms (observation rooms) in California which are still rare today.
