Message from the Head of School



Welcome to The Lang School, where you will find that being exceptional is not only recognized, but celebrated!


It is my pleasure to be the Head of School, Interim this year. Every morning, I greet the students as they arrive in the morning, either by bus, train or even by bike! We are located in Lower Manhattan in the Financial District,

right at the famous Charging Bull statue. We think that the statue is an apt icon for our students who are unique and resilient and with the support of our incredible faculty are focused on optimism and growth. 


Our school is driven by a purposeful mission and an unwavering commitment to our twice exceptional students and their families. I delight in partnering with our highly trained staff who each day support the development of skills and strategies called for by our learners' giftedness and areas of challenge. Where students often stood out for the wrong reasons in their prior schools, students at The Lang School fit in so that learning, growth and a positive sense of self can be cultivated. These highly promising learners have teachers and supporting staff members who appreciate and empower them and their talents. It is a thrill to be part of this school. 


I invite you to come see The Lang School in action. Lang's vivid and dynamic outward impression is indicative of the great things going on inside the classrooms. 


With warm regards, 


Dr. Sue Groesbeck

Ongoing Head of School Search

Board Chair Gavin Simms announced to the community on November 22, 2022, that Mark Otto has been appointed by the Lang School Board of Trustees to serve as our next Head of School. Mark is a visionary educator, proven administrator, and collaborative community builder. The Search Committee unanimously recommended Mark to the Board, who voted that he should succeed Sue Groesbeck, our current Head of School. Mark will join Lang and assume the Head of School role in July 2023. See Mark's bio below.

Throughout the search process, Mark consistently demonstrated exceptional interpersonal skills, a genuine warmth, and an openness to considering a wide range of views and perspectives. He impressed the Search Committee and Board of Trustees with his understanding of The Lang School and our mission and culture. He is an experienced educator and administrator who will bring vision and passion and community building along with an evidence-based approach to his new role. In his words, he will 


…work hard to ensure that Lang continues to be a school community that meets the needs of all our students and families. I will advocate on behalf of 2e students and spread the word of the student-centered, innovative work we are doing at Lang, as a model for what is possible throughout the country. I will also continue the work that has already begun to ensure Lang is a place for everyone and that we expand our understanding of diversity, equity, inclusion and belonging to identify our areas of strength and where we still have room to grow.


His colleagues had this to say about Mark – 


He is a visionary. Anything you give him to do, he will create a vision around. He is passionate about young people and education, particularly vulnerable populations. He believes staff should be empowered to make decisions.

Everybody loves Mark. Not only is he funny and articulate, but he is also just smart and takes time to build relationships with people. Even while teaching in a challenging community he can find humor in the work. He gets along with folks. He is trusted and people knew he could support them when needed.


The feedback from those of our community who met with Mark agreed with those sentiments. He was described as 


A real leader, forward thinking, strategic, respected.

I believe Mark is highly qualified for the Head of School position and cannot think of any questions about his ability to succeed at Lang.


Mark has committed himself to getting to know our community, to maintaining and strengthening the mission and culture of the school and helping us all create the next chapter of Lang together.

Board Chair Gavin Simms commented 


I would like to thank the entire Lang community for your participation in this search process. The shared vision that we collectively defined at the outset of the Head of School search has guided us through every step of the process, and I’m thrilled with the outcome. In addition, I especially thank the Search Committee for their tireless commitment to the intense and demanding work required of this critical decision.


We will be in touch during this school year as we finalize plans for introducing Mark to the Lang community, and we look forward to seeing him at our school frequently over the 2022-2023 academic year.
