Investing in Purpose

The Hilltop is strengthened each year by our dedicated families, alumni, grandparents, faculty, and friends. Together, you help SLS remain vibrant and growing. We invite you to explore the many ways to give.

SLS Fund

The SLS Fund (formerly the Annual Fund) is the heart and soul of our fundraising efforts, bridging the gap between tuition and the actual cost of a student’s education.

Your participation matters.

The SLS Fund succeeds only as a collective effort; every gift, regardless of size, makes a tangible difference. Even a small increase in the percentage of participation or the average size of a gift can have a big impact on our success.

Your gift makes a difference by supporting:

  • competitive salaries and benefits to attract and retain the best faculty
  • classrooms equipped with state-of-the-art educational tools from projection systems to language lab materials
  • community service initiatives and programs
  • professional development and leadership opportunities
  • our beautiful campus and facilities

In addition, outside funding sources look closely at our alumni and parent participation when reviewing our grant proposals.

Our superb faculty, innovative programs, caring community, and remarkable range of opportunities in athletics and the arts would not be possible without the generous support of our alumni, parents, faculty, and grandparents.

Senior Gift

The Senior Gift is an SLS tradition providing parents a meaningful opportunity to honor their graduating seniors with a legacy gift to the School.

Parents of the graduating class join together to honor their graduating seniors with a unique and valuable legacy gift to the School. We are incredibly grateful to the senior parents of past classes for the generous gifts that have established endowments, contributed to program growth, and provided funding for new facilities—each gift benefiting future generations of SLS students.

Endowed Funds

Endowed funds provide dependable annual income for SLS. Some funds are unrestricted, others support specific student, faculty, or programming initiatives. Earned interest supports the operating budget and helps to minimize tuition increases.

We invite you to review SLS’ endowed funds and hope you will consider contributing to an existing fund or establishing a new one. For more information on establishing an endowment, please contact the Development Office at 203-801-4857 or [email protected].
