Dear Girls Prep Lower East Side Middle School Families,

Welcome to the 2018-19 school year at Girls Prep Lower East Side Middle School! I am honored to lead the 5th-8th grade middle school campus of NYC's first all-girls, tuition free, public charter school in the vibrant and diverse Lower East Side community, and to work alongside Rebekah Adamek, Principal of Girls Prep Lower East Side Elementary School. When I joined this team in 2013 as the 7th grade English teacher, I was drawn to our network’s commitment to create a “warm and joyful culture of rigor” and to graduate alumna who are empowered to make choices that will make our world a better place. At Girls Prep, we know the importance of educating girls in our society, of cultivating their voices and confidence, so that when they leave our doors they are prepared to face any challenge that comes their way. It is because of my commitment to our mission that I chose to teach at Girls Prep and why I feel humbled and privileged to lead this community.  

When you walk into our building, you will see and hear how our students and staff live our mission everyday. You will hear scholars  engaging in text based discussions, thinking critically about what they have read, and crafting arguments rooted in evidence. You will see our scholars working in collaborative groups to solve real-world problems and challenging each others’ thinking. You will see our commitment to STEM as our scholars engage in daily science classes where they apply their core body of knowledge in hands-on experiments and lab work on the BioBus. You may also see our 8th graders learning computer science through our partnership with Cornell Tech. This commitment to STEM has led to 100% of our scholars passing the Living Environments and Algebra 1 Regents Exams. You will also see the photos and words of our namesakes that include Maya Angelou, Michelle Obama, Hillary Clinton, and Sandra Cisneros; authors, poets, activists, and changemakers who have made this world a better place, and in whom our girls can see themselves and the possibilities that lie ahead. You will hear students and staff speaking about and demonstrating our core values of sisterhood, merit, responsibility, and scholarship. It is these core values that ground us as a community and build the strong character needed for our scholars to face any obstacle with resilience.

It is because our scholars are challenged to think and work hard every day that they are prepared to excel in leadership development programs that place scholars in top performing schools. These programs include Prep for Prep, TEAK, Breakthrough, Oliver Scholars, and A Better Chance. Our scholars also have access to pre-college immersive experiences at Cornell University and Stephens College, which has a 4-year full scholarship reserved annually for a Public Prep alumna, and at the U.S. Naval Academy in Annapolis, Maryland. Moreover, 2018 also marks the sixth consecutive year in which 100% of the Girls Prep 8th grade graduating scholars were accepted into high-quality, "right-fit" college-prep high schools that will ensure the scholars remain on a path to college completion. Girls Prep alumna now attend 33 of the top nationally ranked public high schools in NYC (by US News & World Report) and a range of top parochial, private and public high schools, including Phillips Exeter Academy, Deerfield Academy, Bard Early College High School, Manhattan/Hunter Science School, Beacon, and Sacred Heart Academy.

On behalf of our entire team, I’d like to thank you for partnering with us for what will be an incredible school year together and entrusting us with the people you hold most dear. Our North Star to College Completion is only possible because of the commitment of students, families, and staff to work together along this journey. I could not be more excited to get to know your family. I look forward to seeing you at our upcoming family events, so mark your calendars for our Lemonade Social (Wednesday, September 5th) and Open School Night (Thursday, September 20th).

Looking forward to a great year together!
