Our staff is built to teach each student individually, to develop the skills they need to thrive in mathematics, and to foster a love of learning.

Lynn Byfield

Having spent the last decade in education, Lynn has a strong passion and sense of belonging working with students to build their confidence through learning. After seven years as a teacher for Seminole County Public Schools, culminating with her recognition as Teacher of the Year in 2013, Lynn stepped away from the classroom and into her next chapter with a steadfast commitment: “helping children gain the confidence to succeed both inside and outside the classroom.” In 2013, Lynn opened Mathnasium of Lake Mary, in the community that she and her family have called home for the past 30 years, to do just that. Over the last seven years, Lynn and her center have received community and national recognition for their commitment to helping students conquer math through number sense and advocating for their own math skills. Most notably, the Mathnasium of Lake Mary was awarded the #1 Mathnasium in the Nation for “Right Instruction” - recognizing the center for its incredible team of instructors and their aptitude with the “Mathnasium Method” (quite the high praise with over 1,000 amazing Mathnasium’s out there!) In 2020, Lynn was thrilled to open her second center, Mathnasium of Lake Brantley, to continue to give back to her community, advocate for her students, and build strong math students by “making math make sense”.

Pareen has a passion for teaching and loves sharing her knowledge with others.

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
