This diverse, experienced cohort of educators will develop and prepare for executive leadership.  

NSNO is proud to celebrate the first cohort of Greenhouse E3 Fellows. These New Orleans educators are part of the national Greenhouse E3 program, which develops future executive-level leaders for public charter schools. Greenhouse E3 has cohorts in Washington D.C., Indianapolis, and Jacksonville, FL, and is quickly expanding to more states and charter networks nationwide, but it grew from NSNO’s own E3 program. NSNO’s E3 program had three successful cohorts starting in 2020, after which it expanded into “Greenhouse E3,” and is now being run externally by educational leaders who we’ve worked with for many years. We will continue to support their work and steward the New Orleans cohort.

Greenhouse E3’s programming fills a critical role in our system. In New Orleans, we need great leaders teaching students in classrooms each day.  We need great educational leaders on our basketball courts and in band rooms, and we need great leaders serving schools as principals. We also need great leaders running school networks. Charter leaders often support multiple schools at a time–they coach principals, manage executive teams and operations, set the network-wide goals and visions, and are ultimately responsible for the education of all their students.  

NSNO is proud to help support teachers through our New Orleans teacher community and principals through our Novice Leader Academy program. Greenhouse E3 allows us to help support charter leaders as well. Their programming includes personalized coaching, site-visits to top-performing schools across the country, and professional development sessions with a cohort of fellow leaders. 

This year’s New Orleans cohort of the Greenhouse E3 Fellowship includes five strong, experienced educators with a deep commitment to New Orleans’ children.
