Karen LandyKaren Landy, Instructor

Karen is a 34 year veteran middle school math teacher.  She retired from teaching and realized her connection to math was also her connection to kids.  She loves the positive atmosphere at Mathnasium, which reminds her daily of why she loves to teach.

Karen has a way of diagnosing student needs and pointing them in the direction that works best for them, using the Mathnasium Method. As a child she realized that learning was something that needed to be presented in concrete logical ways so that others could "get it". She spent her teaching days developing different ways of understanding math skills and concepts so that every child's learning method was tapped into.  She is a caring and important member of the Mathnasium staff.
