• My name is Mr. Nissenbaum and I am a fifth grade teacher at Stillman School.  I have been teaching the fifth grade in Tenafly since 2005.  I am proud to be a teacher at Stillman Elementary for so many years and I truly enjoy both teaching and learning. I am very passionate about all kinds of music and also play various instruments.  I always look forward to working with and challening my students each year.  If you have any questions or concerns, please email me:  enissenbaum@tenafly.k12.nj.us
