Richard Riordan Primary Center opened in 2003 as a nurturing environment for children in grades TK-1 in the vibrant Highland Park community. Over the years, our scope and focus has expanded to include all elementary grades. It is now the proud home of a Dual French Two-Way Immersion program for grades TK-5 and two Preschool for All Learners (PALS) self-contained classes for students with disabilities.
