From the archives of Pennington’s storied past to classes in world history, Mrs. Gretchen Overhiser has become a multifaceted force at the School: teacher, historian, mentor, and steward of tradition.

Mrs. Overhiser’s path to Pennington was anything but predictable. The daughter of a Navy family, her childhood was marked by movement; California, Georgia, Pennsylvania, South Carolina, and New York were all home at one point or another. That transient lifestyle first drew her to the skies, where she trained and worked briefly as a flight attendant. It didn’t take long, however, before her academic interests brought her back to the ground… and into the classroom.

Armed with a BA in history from the University of Michigan and a master’s in historic preservation from Eastern Michigan University, Overhiser began her professional journey as a curator at the Henry Ford Museum and Greenfield Village. There, she oversaw the museum’s decorative arts and educational exhibits, delving deep into America’s technological and cultural past. She was captivated not just by the grand inventions of planes and automobiles, but also by Henry Ford’s vision: to preserve the history of everyday objects–dishes, tools, furniture–that told the stories of ordinary people and the craftsmanship behind each piece.

After relocating to New Jersey, she began consulting for informal education spaces like museums and zoos, eventually finding her way into formal education through work with Rutgers University. After a career pause to raise her two sons, Marshall and Elliot ’22, and to earn a Masters of Arts in teaching from The College of New Jersey, Overhiser returned to the classroom, first as a substitute teacher in local schools. In 2014, at the suggestion of history teacher Mr. Harding, she applied to Pennington to cover a maternity leave and she has been a vital part of the School community ever since!

Overhiser has taught a wide range of subjects, from American history and global studies to the history of innovation and Middle Eastern history. Today, she teaches world history honors, honors thesis seminar, and organizational behavior—courses that reflect her intellectual range and deep curiosity.

Beyond the classroom, Overhiser’s commitment to preserving Pennington’s legacy has had a lasting impact. When construction of the Kenneth Kai Tai Yen Humanities building began in 2015, she noticed historical materials being discarded and quickly proposed an initiative to preserve them. With the support of Dr. Hawkey and Chairman Peter Tucci, an archival space was eventually created in the library, and Overhiser has since become the School’s official historian. Her work has helped uncover and safeguard countless treasures, from Helen Keller’s signed autobiography to 19th-century student scrapbooks, century-old yearbooks, and memorabilia from one of the longest-running high school football programs in the country.

Her archival work doesn’t just serve the past, but it also informs the future. From digitizing crumbling blueprints to collaborating with operations staff, her work helps support renovation efforts and historical branding, including student-led research into Pennington’s logos for use on School spiritwear.

In recent years, Overhiser has taken on another major responsibility: directing Pennington’s Horizon Program. Designed to prepare seniors for life after graduation, the program includes two weeks of workshops on personal finance, LinkedIn profile creation and resumé-building, civics, car maintenance, and wellness. This is followed by two weeks of real-world experience through internships, both near and far, in fields ranging from environmental work with UNICEF to pharmaceutical marketing, dentistry, politics, and even professional sports.

For Overhiser, the Horizon Program represents a vital bridge between education and adulthood. “It helps students understand what matters to them and how to present themselves as someone who has something to offer,” she says.

Overhiser’s contributions to the School don’t end there. Since 2024, she and her husband have also been part of the School’s residential life team, living in a boys’ dorm and offering guidance, support, and plenty of good humor to the young men under their care.

Whether she’s guiding a class through centuries of global history, uncovering forgotten stories from Pennington’s past, or helping seniors step into their futures with confidence, Mrs. Overhiser brings remarkable depth and care to everything she does. The Pennington community is lucky to call her one of its own!
