 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, including English and Portugese. 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.
 

Center DirectorGiulio Helmsdorff, Consultant and Mentor

Since Giulio was a kid, he enjoyed building and taking apart anything he could get his hands on. Math and physics became more than a subject in school, but a way to understand the world around him. He graduated as a Mechanical Engineer in 1993 and worked for nine years in the manufacturing industry designing tools and parts for cars. He earned an MBA degree in 2003 from Babson College in Massachusetts and worked in two technology startups before finding Mathnasium.

Giulio has always enjoyed teaching. Before any important math test in high school there were always three or four classmates looking to him for help. As early as his first year in college, Giulio was teaching math and physics or working as a teaching assistant.

Giulio is fluent in Italian and Spanish, and is a trusted mentor to both Sean and Cam.

"In good and bad times the best gift parents can give their children is mind and soul for their journey. Mathnasium is the best gift for a child's mind. A little Mathnasium soul also comes along."


Rosalie Hopkins, Assistant Center Director

 

Rosalie Hopkins is a veteran educator, having taught middle school, high school, and university students in three states. After teaching in public institutions of learning for more than 10 years, she founded a company dedicated to training adult learners. Rosalie received her bachelor’s and master’s degrees from the University of Delaware, and her doctorate in Education from the University of Georgia.

“Here in Georgia, through Hope scholarships, our children are fortunate to have almost free access to many first-rate colleges. universities, and institutes of higher education. Helping children understand and use math from an early age is the best way to ensure that they will be able to take full advantage of this tremendous resource.”

Of the Mathnasium program she says, “If the United States is to remain competitive in the global economy, we will surely need a workforce that is mathematically proficient. Helping youngsters ‘flex their math muscles’ from elementary school on provides the foundation for learning and the confidence to tackle advanced mathematical concepts.”

 

Assistant Center DirectorNina Bernardi, Consultant and Mentor

 

Nina has a Bachelor and Master Degree in Fine Arts.

As a member of the Mathnasium team, she uses her longtime experience to advise and mentor Sean and Cam and helps maintain the operational excellence of the Learning Center. She also brings an invaluable approach to teaching math for students who feel more comfortable of expressive and creative tasks (a “right side of the brain” preponderance). Nina has reached the highest certification in the Mathnasium Method.

Of the Mathnasium program she says, “It is important to realize that some students are much better at creative and expressive tasks and an instructor needs to play to those strengths to teach logical and analytic thinking”
