Ripsime began her journey as an educator while still in high school, tutoring other students after school and quickly recognizing that she had a knack for communicating complex and abstract ideas in an easy-to-understand way and a passion for tailoring her efforts to each individual in a way that inspired interest, confidence, and a desire to advance learning.

In addition, she works to strengthen executive functioning abilities through developing analysis, synthesis, problem-solving, organization, and follow-through skills that are fundamental for lifelong achievement.
