Rio del Sol Administrative Staff

Dr. Ryan Emery


At Rio del Sol, we value all types of learning and intend to foster growth in each child.  We have established guidelines, routines, character education and academic curriculum to help your child master grade level standards.  In order for each child to attain mastery of challenging State Standards, it will take great effort on the part of teachers, families, and students.  We know that if we work together as a team, your precious children will grow by leaps and bounds.

We strive to support children socially and emotionally as well help children develop academically.  We are in the second decade of the 21st century and it is our obligation to teach 21st century skills.  We intend to teach children how to think critically, how to be problem solvers, and to understand the nuances of the English language.  Students will learn academic skills in all core areas, with an emphasis in literacy.  We will utilize our 1 to 1 computing devices and interactive televisions that we have on campus so students can access the world from their classrooms.

While academic excellence is our focus, we also encourage and teach character education as well as leadership.  Additionally, through the execution of thoughtful lessons, we will build capacity in our students so that they become life-long learners and are prepared to meet the demands of an ever-changing world.  Critical thinking, creativity, communication, collaboration, and Caring (the 5 Cs) will be focal points across content areas.  At Rio del Sol, we have high expectations for our students.  We share a fundamental belief that students will rise to the occasion to meet the expectations of the adults that care for them.
