"AoPS Academy is such a valuable resource for my two daughters and our family.  We kept hitting brick walls with our former school and the Director of AoPS Academy was the first person to honestly explain to us options and provide us with information so that we could make informed decisions about their education.  For that we are forever grateful and trust him beyond measure. AoPS Academy is far more than just an after-school academic training center. They have gone above and beyond to help our children's talents develop into their full potential.  Art of Problem Solving Academy will continue to be a key part of our long-term education plan.  The results have been amazing! They are truly my children’s first school, even though they are an after-school program!"
