At Riverdale, we have a robust faculty, staff, and administration so that we can meet the needs of our students and their families. Our class sizes are small, and students have access to many adults who can support them during their educational journey through the school. Parents/guardians will get to know their students’ teachers through our Back to School Nights and Experience Riverdale Day. In case you need to reach someone at School, we have put this webpage together to help.
