Mr. Arnaldo Almaguer

I have been teaching 5th grade since 2006 and enjoy being the last grade that prepares our students for the challenges that await them at Tenafly Middle School.  In the summer months, I have served as a teacher, Assistant Director, and Director of the Tenafly Summer Enrichment program. In addition to teaching, I have coached baseball at Tenafly High School (all levels, from 2009-2019). During Covid 19, I was the coordinator for English Language Learners' supplemental virtual instruction. I also do work as a Gifted & Talented teacher for Mathematics. I am honored to serve the community of Tenafly. My preferred method of contact is:
