SOS LEADERSHIP
Sandra S. Mitchell
Alumna, Episcopal Leader, and President of the Save Our St. Margaret’s Board
A proud 1964 graduate of St. Margaret’s School, Sandra S. Mitchell has spent a lifetime rooted in the values of education, faith, and service. Baptized and confirmed at Bruton Parish Church, Sandra was raised in a devout Episcopal family that instilled in her a deep sense of purpose and responsibility. After graduating from St. Margaret’s alongside her twin sister, Sherry, she pursued a career in physical therapy and healthcare administration, Sandra was a pioneer in her field, developing the physical therapy program at the University of Evansville, helping to establish some of the nation’s first hospital-based rehabilitation units and freestanding rehabilitation hospitals, and serving as a sought-after national speaker on rehabilitation care.
Sandra served on the St. Margaret’s Board of Governors from 1994 to 2002 and has remained a dedicated supporter ever since. In 2025, she assumed the role of President of the Save Our St. Margaret’s Board, where she leads a growing coalition of alumnae, parents, and friends working to ensure the School’s continued operation and to uphold its rich traditions.
Her commitment to St. Margaret’s is both personal and enduring. She credits the School with shaping her faith, character, and leadership, and she is passionate about preserving that same opportunity for future generations. Sandra has also supported recent revitalization efforts at the School, including its new Rowing Academy, for which she pledged funding to retrofit a boathouse in Latane Hall.
Through her decades of service to both the Episcopal Church and her alma mater, Sandra remains a steadfast voice for the values that define St. Margaret’s: excellence, integrity, and the development of confident young women grounded in purpose.
Brooke Trible Weinmann
Alumna, Advocate, and Educational Leader
A proud native of Essex County, Brooke Trible Weinmann is a graduate of St. Margaret’s School, where her passion for girls’ education first took root. She went on to earn an A.B. in History from The College of William and Mary and an M.B.A. from Harvard Business School. Early in her career, she was selected as a Commonwealth Intern for Virginia State Government and later co-founded Pacesetters, Inc., a Richmond-based executive search and management training firm, where she served as vice president. After graduate school, she joined IBM in Atlanta.
Brooke’s enduring commitment to educational equity is reflected in her role as co-founder and founding trustee of the Atlanta School for Girls—Atlanta’s only grade 6–12, all-girls, college preparatory, independent, non-sectarian school in the city’s recent history. The school served hundreds of young women over two decades before closing in 2024. Brooke now holds the title of trustee emerita.
In her current role, Brooke designs and manages luxury travel experiences for a leading international tour company. Her extensive leadership and volunteer work spans mental health, secondary and higher education, numerous nonprofit boards, and the Episcopal Church.
Brooke resides in Atlanta, Georgia, with her husband, Winston Weinmann, and is the mother of four adult children. Through her continued support of St. Margaret’s and her advocacy for girls’ education, she remains deeply committed to nurturing the next generation of strong, educated women.
Roger Sanders
St. Margaret’s Grandparent and Lifelong Advocate for Justice and the Underserved
A longtime ordained Presbyterian lay pastor, Roger Sanders has dedicated his life to serving others through both ministry and the law. For 51 years, he worked as a Texas trial lawyer and later as a federal magistrate judge, consistently fighting for “the little guy” and upholding the values of fairness, dignity, and compassion. His career has been marked by a steadfast commitment to justice—especially for those society too often overlooks.
Many years ago, he was entrusted with the care of his young granddaughter. Seeking a place where she could grow in both strength and character, he chose to enroll her at St. Margaret’s School. Since that time, he has become a passionate booster and active fundraiser, firmly believing in the School’s mission to nurture confident, good-hearted young women.
“St. Margaret’s gave my granddaughter more than an education—it gave her a foundation,” he says. “And I want other girls in need of that same opportunity to find it here.”
His story reflects the heart of Save Our St. Margaret’s: preserving a school that transforms lives through education rooted in service, compassion, and leadership.
Margaret Barlow
Alumna, Educator, and Advocate for the Future of St. Margaret’s
A native of Irvington, Virginia, Margaret Barlow was raised in a family deeply rooted in education and community service. Her parents were among the founding families of Chesapeake Academy, where she attended through eighth grade before enrolling at St. Margaret’s School. A proud member of the Class of 1975, Margaret credits her time at St. Margaret’s with shaping her academic foundation, moral compass, and enduring belief in the power of all-girls education. She went on to attend Hollins College.
Since relocating to Louisville, Kentucky in 1978, Margaret has remained a tireless advocate for educational opportunity and social impact. She has spent the past two decades volunteering at West End School, an independent school serving at-risk boys in pre-K through 8th grade. Her work there reflects her lifelong dedication to lifting up students through mentorship, service, and sustained philanthropy.
Margaret and her husband are the proud parents of four children and grandparents to ten. Her commitment to Save Our St. Margaret’s reflects her belief that girls today deserve the same transformative experience she received—a place where they are known, supported, and equipped to grow into thoughtful, confident young women.
