A Message to the Blind Brook Community

To the Blind Brook Community,

As this school year unfolds, I have spent some time reflecting on my journey at Blind Brook and on the timing of an important personal decision I would like to share. I will be retiring from my role as Principal of Blind Brook High School effective July 1, 2026, bringing to a close a chapter that has meant more to me than I can easily put into words.

This year marks my 40th year in education, including 31 wonderful years in the Blind Brook School District. I joined the Blind Brook school community in 1995 as a Social Studies teacher, and over time, had the opportunity to serve as Department Coordinator, Assistant Principal, and most recently, Principal. Each role allowed me to grow, to learn, and most importantly, to work with extraordinary people.

Throughout my time here, I have had the privilege of working alongside talented educators and collaborating with dedicated administrators, superintendents, and Board members. I am deeply grateful to the thousands of students I have taught and to the families who trusted me to care for, support, and educate their children. That sense of gratitude extends beyond my professional life, as Blind Brook has also played a deeply personal role for my family.

More than 30 years ago, my wife, Stephanie, and I chose Rye Brook as the place to raise our family. Both of our daughters, Melanie and Chloe, attended Blind Brook schools from elementary through high school. Along the way, I even had the unique (and unforgettable) experience of teaching my older daughter in middle school, along with the children of many close friends.

As I look ahead to the end of this school year, I do so with tremendous gratitude. Blind Brook has shaped me not only as an educator, but also as a husband, a father, and a member of this community. While Blind Brook High School will no longer be my workplace, Blind Brook will always be my home—a place filled with friendships, memories, and people I care deeply about.

Thank you to the administration for trusting me with the opportunity to lead the high school, and thank you to the faculty, parents, and students for your support over the years. Blind Brook is a truly special place—an exceptional community and a wonderful school district—and I am proud to have played a small part in its story.

With gratitude,
Mark Greenwald
