Steve & Sandy Massey

Hello. We are Steve and Sandy Massey, owners/operators of Mathnasium of Oviedo. Our relationship with Mathnasium began in 2012 when our son enrolled in Mathnasium to improve his Algebra skills. Our story may be similar to yours. After many evenings of ineffective homework help and frankly, lots of family stress, we went in search of math tutoring for our son. What we found was a math learning method that turned our son’s grades around in a few short months and profoundly spiked his overall confidence and interest in math. The Mathnasium method proved to be much more beneficial than one-on-one tutoring and improved our family life tremendously. We were so impressed with the Mathnasium model and the successful method of making math make sense that we open our first center in Oviedo in 2013. Today we love sharing the Mathnasium methods at four personally owned centers in Florida.

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.
