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.

Alex Guppy

Alex received his Bachelor's degree in Mathematics from Kalamazoo College in Michigan. Shortly after graduating, Alex moved abroad to teach English in Taiwan - an adventure turned odyssey that lasted the next six years. When he was not teaching and having fun with his students, he was exploring the mountains and streams of the island. Eventually, home called and Alex returned to the States in 2013. In the Fall of 2014, Alex visited Chattanooga for a rock-climbing trip. As the season passed by and frost began to accumulate on his tent each morning in Prentice Cooper State Park, Alex contemplated returning home to Michigan for the holidays, but then applied for a center director position at Mathnasium on a whim. He cannot help but look back on his humble beginnings as a math tutor here in amazement. At the beginning of 2018, Alex became the sole owner of both Mathnasiums in Chattanooga and has since gone on to open or purchase three more in Williamson County. Alex is honored by all of the parents who have entrusted the safety and education of their children to him over the years to help him realize his dream of owning his own business. He is looking forward to providing math homework help to many more children in the coming years as he works hard to provide a wonderful experience for his students and reach their full potential in math.

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