Hello! I'm Jordan Kaminski, Center Director of Mathnasium of Oconomowoc, your neighborhood math-only learning center. We help kids in grades K-12 understand math by teaching the way that makes sense to them. While our center is currently under construction, we'd love to pre-enroll your child at Mathnasium of Lake Country in Hartland to support them right away!

We specialize in math-only instruction with a focused, caring, and fun learning approach that delivers results.
We proudly serve local communities and schools, including:

  • Oconomowoc, Summit Corners, Monterey, Ixonia, Stonebank, Wales, Concord, Dousman, and the surrounding communities
  • Oconomowoc Area School District (Oconomowoc High School, Nature Hill Intermediate, Silver Lake Intermediate, Greenland Elementary, Ixonia Elementary, Meadow View Elementary, Park Lawn Elementary, Summit Elementary)
  • Stone Bank School District
  • Kettle Moraine School District
  • Adeline Montessori, Holy Trinity Lutheran, Lake Country Classical Academy, St. Jerome Parish School, St. Matthew's Lutheran, St. Paul's Evangelical Lutheran
