Reasons to consider Absolute Value Tutoring

We are small and plan to stay that way. Think of us an an educational boutique. Our classes are either one-on-one or small groups with a maximum of six students.

The Latin definition of the word “tutor” is “to guard or watch.” For this reason, we hire teachers who are passionate stewards of education. All of our tutors are professional educators who possess mandatory state and federal clearances.
