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.
