Mr. Nelson Greene

I’m very excited to join the staff of Ron Brown College Preparatory High School for the 2018 - 2019 School Year. It has been my pleasure to work in DC Public Schools for over fifteen years in many capacities, with the common goal of educating our students holistically. Prior to joining the Leadership Team at Ron Brown HS, I served as the Pathway Coordinator at F.W. Ballou SHS, where I focused on preparing our students who were off track academically to improve their effort and seek additional support in order to matriculate through high school. Forging relationships and empowering youth is at the core of my everyday work, and it is the foundation of my passion for education. My educational experience includes a Bachelor of Science from Morgan State University along with an MBA from Trinity University of Washington, DC. I look forward to continuing to serve the youth and the families of DC Public Schools.

Outside of work, I enjoy spending time with my wife and son as we explore the many things to do in the Washington, DC area.


Teacher Leader Innovation (TLI) ~ Meet our TLI Team

The Teacher Leadership Innovation (TLI) program within DCPS offers excellent teachers the opportunity to spend part of the day teaching and part of the day leading other adults in the building in enhancing the educational experiences for all students. TLI Teacher Leaders are school-based employees who teach for at least 50% of the day, and spend the remainder of their day coaching and leading their peers. TLI began in 2013 and continues to be an integral leadership position at schools across the district. This school year,  at Ron Brown, there are 3 TLI Teacher Leaders leading LEAP Teams in the contents of Math, Science, and English Language Arts (ELA).   

TLI Teacher Leaders lead teachers through a cycle of content specific seminars, in which they develop teachers’ content knowledge, support their planning, and guide the analysis of student work tied to the DCPS curriculum. TLI Teacher Leaders also often provide coaching support for teachers on their team by using a variety of coaching touchpoints, including observation and debrief, co-planning, or modeling and debrief.  

In addition to coaching for content support, our TLI Teacher Leaders will support teachers in fulfilling the mission and vision of Ron Brown by providing coaching supports that ensure all teachers are providing rigorous and culturally responsive experiences that prepare Young Kings to act as reflective agents of change to solve problems that impact their diaspora. 

Ms. Stephanie Johnson

Ms. Johnson began her career teaching middle school literature in 2006 in South Carolina. After relocating to DC in 2010, she taught English language arts at Eliot Hine Middle School for seven years before joining the Ron Brown community as a ninth grade English teacher. In addition to teaching English, she has held multiple leadership roles at the school and district level. This year, Ms. Johnson will be broadening her work at RBHS to serve as the TLI Coach for the English department. In this capacity, she will support the teachers in the English department in implementing rigorous and culturally responsive instructional practices that allow our students to master the district curriculum. Ms. Johnson believes that we all have the capacity to author our own life stories. Through her work both inside the classroom and in the broader English department, Ms. Johnson’s goal is to equip our Young Kings with the tools they need to be the hero of their life stories.

Ms. Ashley Kearney

Ms. Kearney is a proud member of Delta Sigma Theta Sorority, Incorporated. She lives by Luke 12:48 which states, “For everyone to whom much is given, of him shall much be required.” She returned home to DC in 2012 to serve her community as a Teach for America DC Region Corps Member. During her first year in the district, she was awarded the 2012 New Teacher of the Year, 2012 7th Grade Math Teacher of the Year, and 2012 Overall Teacher of the Year at Ronald H. Brown Middle School.   

As a devoted community organizer and education advocate for underserved students in DC, Ms. Kearney used her former chair role for TFA Collective DC to help launch the Be the Change Scholarship Program to provide funds for student of color in financial need, current co-chair position for DC Education Coalition for Change to include the voices of students and families in securing political wins that helped shape policy for better outcomes for students east of the river, and served on the SY 18-19 Chancellor’s Teachers’ Cabinet to elevate teacher voice in helping to shape the future of DCPS.  

She hopes to continue to use this role to cultivate a culture of competency, curiosity, and collaboration whereby all math teachers feel supported in providing urgent, high quality and personable instruction that ensures every mathematician will experience a cohesive and joyful math journey and are equipped for societal change.
