For the right students and families, Millbrook is better by design in important ways and the best boarding school choice in the U.S. Located ninety miles north of New York City, with easy access by train, Millbrook benefits from the energy and culture of America`s most important city and the incredible natural beauty of the Hudson Valley.
Our beautiful 800-acre campus is expansive yet intimate, traditional yet contemporary; our setting is perfectly designed for learning, inspiring immense life-changing ideas.
We are a powerful, intentional, engaged academic community, and students learn how to think and how to lead.
Determined and resilient, they create their own paths and work tirelessly to reach their goals.
Millbrook students explore broadly, develop their passions, and build on their strengths.
Our faculty are devoted to helping all students discover their true best selves in lasting ways as they guide each student through his/her own personal development plan.
Our student-athletes compete at the highest levels against schools twice our size and learn teamwork and creative problem-solving in the process.
Our exceptionally equipped and robust arts program is unmatched by most other independent schools, and professional artists lead our classes, offering inspiration and superior instruction.
Millbrook`s tradition of service and stewardship is manifested in a real and relevant service program unlike any other, and students make real and meaningful contributions to the life of the school every day.
Here we have a farm to feed our students, we source 100% of our energy from the sun, and our students care for 80 species, including eight endangered species, in a world-class zoo.
We are 330 students strong, and our intentional size allows us to push each student to achieve his/her full potential and personal best.
This happens only at Millbrook, an original American school with a global perspective, where every student`s education is Better by Design.
