Under the leadership of Ryan Costa, the center has become a hub for K-12 students in Portsmouth and beyond, offering personalized tutoring that helps students build their math skills, boost their grades, and, most importantly, gain lasting confidence in their abilities.
A Proven Approach: The Mathnasium Method™
At the heart of Mathnasium’s success is its proprietary Mathnasium Method™, which blends personalized learning plans with engaging teaching techniques. This method is designed to cater to each student’s unique learning style, ensuring that no one is left behind. Costa emphasizes, “Our method builds confidence first. When students feel confident, they’re motivated to learn and succeed.”
This individualized approach begins with a diagnostic assessment to identify a student’s strengths and weaknesses. From there, a customized learning plan is created to reinforce fundamental concepts, fill in gaps, and advance students’ understanding of math. Mathnasium’s trained tutors specialize in a variety of math topics, from Algebra and Geometry to Trigonometry and Calculus, helping students at all levels—whether they’re catching up or aiming for top scores.
Mathnasium’s effectiveness is reflected in the results: 94% of parents report an improvement in their child’s math skills, and 93% say their child’s attitude toward math has improved. Moreover, 90% of students see an increase in their school grades.
Making Math Fun: The Mathnasium Difference

Whether students are struggling with the basics or advancing to higher levels of math, the tutors at Mathnasium are patient and understanding, providing personalized attention that makes a meaningful difference.
Students aren’t the only ones who benefit; parents also see significant improvements. One parent shared, “My daughter loved every session. I noticed her skills getting sharper, and she seemed more confident in school.” This feedback is just one example of the transformative effect Mathnasium has had on local students.
