About our Principal


David Coster

I am proud to celebrate my seventeenth year in public education.

I began my career, teaching high school mathematics in Basking Ridge. I joined the Madison High School faculty in 2007, leaving in 2011 to become the Math and Science Supervisor in Cedar Grove. In 2013, I returned to Madison and proudly served as Assistant Principal of the Junior School. I feel very fortunate for having been selected as Principal last year. Together, with our new Assistant Principal, Mrs. Lubieski-Hutmaker, I look forward to continuing the work that has meant the world to me, supporting the students of the Madison Junior School.
