 Sean Dolan, Co-owner and Center Director

Sean is a math enthusiast from way back. In high school, he attended the Georgia Governor's Honors program in math, won the National Beta Club award for Mathematics, and then went on to major on Mathematics at the College of William and Mary in Virginia, where he met his eventual business partner Cameron Nimmo. Since then, he's spent most of his career in software development for telecommunications technology companies, with occasional stints as a part-time math instructor at Chatahoochee Tech. Now, he is excited to begin a new kind of career with his first love, mathematics, and really looks forward to sharing with kids how much beauty and fun there is in learning math.

Cameron Nimmo, Co-owner and Center Director

Cam is the son of a math teacher, but he did not immediately follow in his father's footsteps.  At the College of William and Mary, where he and Sean first met, Cam studied languages. He is fluent in several languages. The early part of his professional life was spent in the financial industry, but after few years, he got involved in education.  This led to over twenty years of teaching and then running his own school.  And now, his involvement in Mathnasium pleases his father to no end.

Math is such a cool subject, in my opinion, because there is more than one way to arrive at the correct answer unlike many other subjects. Mathnasium teaches students the understanding behind why we do what we do in a math problem. The method really helps students out in the long run because they will fully understand mathematical basics and build on these as they progress in math throughout their school years.
