Welcome to Siena Tutors

Siena Tutors provides individual instruction with experienced teachers to students throughout the United States in grades 3-12. Siena Tutors is an initiative developed by The Siena School, a leader in educating students with language-based learning differences. Siena Tutors allows us to expand our service to students anywhere who would benefit from working one on one with experienced teachers who use research-based, best practices to help students learn.  

We focus on each student’s unique needs and potential for growth in core academic subjects including reading, writing, math, science, and Spanish. All students can benefit from Siena Tutors, and our instructors specialize in working with students who have language-based learning differences, such as dyslexia. We also specialize in students who need extra support with executive functioning.

Siena Tutors provides virtual instruction as well as in person instruction for those in the Washington, DC, metro area. Currently, all instruction is virtual for public health safety.
