Mike & Joanna Ammer

As the Fixed Operations Director for two large successful Chevrolet dealerships and multiple Import dealerships in Illinois and Indiana, Michael has always had an active interest in mathematics. He began his 32-year career in the automotive industry as a car porter and through hard work and determination, became the Director of Fixed Operations successfully managing all aspects of the Service, Parts and Collision centers within the two dealerships. Joanna has been in the Veterinary Industry for over 25 years working as Hospital Operations Manager in both private, corporate, and non-profit veterinary practices. Michael and Joanna have four children of their own, two of which struggled with math, and had Individualized Learning Plans in school. They understand firsthand how this can affect the entire family and only wish that Mathnasium was in this area at the time their children needed extra help. After researching the Mathnasium method and learning how it could benefit children Michael and Joanna made a decision to open their own learning center which meant a career change for Michael. As scary as that was, they knew that parents and students in Crystal Lake and the surrounding areas would benefit from this endeavor. They found there were no other Math learning centers in the area and made a decision to locate their Mathnasium center in the heart of Crystal Lake. One of their goals is to create a center where students experience how much fun math can be and realize the potential that math skills can unlock. Michael and Joanna believe the Mathnasium method will deliver on this goal. They realized that opening a Mathnasium center would allow them to combine their love of children and math while providing a valuable service to the community. They are focused on hiring and supporting only the best math instructors, and look forward to helping children in the area continue to improve and excel in math proficiency and develop a strong sense of numbers. For them, the best part of working with children is seeing the joy in their eyes when they finally get to that "AHA" moment, after grasping the simple concept behind that tough looking math problem.
