School Leadership

Just over one hundred years ago, Samuel and Mary Middleton had a vision: to develop a school on the Corsica River that would provide students with a personalized and rigorous academic experience, a strong sense of community, and a focus on the balanced development of mind, body, and spirit. A century later, and now with a unique emphasis on global and environmental leadership, these values still endure in our school.

TGS draws students from six Maryland counties and Delaware, and with a generous financial aid budget, we attract some of the strongest students in the region. As a school, our emphasis on community is our greatest strength. Students learn quickly that, with small classes and a relentlessly personalized experience, the opportunities for intellectual inquiry, leadership, service, artistic expression and athletic accomplishment are inexhaustible. Guided by a committed, caring, knowledgeable, and talented faculty, each student is challenged to develop their unique intellectual “voice”, and we seek to bring out the best in every student. Each day, TGS environment is characterized by a culture of high expectations, and we believe that learning to be a good person is as important as learning to be a good student. Our school’s values are embedded within the traditional Eastern Shore values of family, courtesy, respect, and a reverence for the natural world. Thus, when we talk with our students about moral and ethical development, we don’t focus on rule-based language, but instead the language of values. Each year, our students recommit themselves to our “Responsibilities of the Community” and they respond by treating each other with an unusually high degree of respect, tolerance, and kindness.We look forward to welcoming you to our campus, and please take some time to tour our website in earnest.
