Embedded Image for:  (202311816360856_image.jpg)

I am so excited to be on this journey with our students, staff, families, and our entire River Islands community. Our RIHS staff is here to support and encourage our students to be the best version of themselves as they work towards achieving their high school and post-secondary goals.  We work hard to prepare our students to be college and career ready as we strive to create a learning experience that is highly personalized, filled with rigor, relevance and is driven by student interest.
