Peter Briggs was named the third Head of School at Greenhill in the fall of 1992. His eight-year tenure kicked off with the Reach for the Stars capital campaign which funded the new Levy Middle School and Three Chimneys buildings, the renovation and expansion of the Agnich Science Center, and the repurposing of the existing Levy Middle School as the new Fine Arts Building. Briggs also oversaw changes to division schedules, programmatic and organizational changes that strengthened the authority and accountability of the division heads, and commissioned a committee to standardize the school’s image, which resulted in the first published Graphic Standards and Style Manual for Greenhill. In the spring of 1999, Briggs announced his retirement and was met by a standing ovation in recognition of his many accomplishments. Greenhill honored Briggs at Homecoming in 2000 by dedicating the Briggs Clock Tower located in the Foote Quadrangle. Briggs passed away on July 25, 2014. |

Sally Estes, parent of Risser '83 and Kris '80, served on the Board of Trustees from 1976 to 2012, and served as Board Chair from 1983 to 1986. In the mid-1970s, Sally is credited for starting what is now known as Employee Appreciation, by spearheading an entire Teacher Appreciation Day designed to thank the teachers for their dedication to the students. More notably, as Board Chair, Sally signed a 99-year land-lease agreement with Trammell Crow Company on January 7, 1985. The lease of the parcel of land adjacent to what is now Midway Road was the culmination of a two-year process where the Land Lease Committee evaluated proposals from a number of firms. The lease gave the School a source of long-term income to bolster the School’s finances, making it more competitive with other schools in town. Later in 1997, Greenhill sold the lease to Cardinal Capital Partners, Inc, which more than doubled the School’s endowment at the time of the sale. Sally’s leadership grounded the School financially, ensuring that it would continue to serve students for years to come. To honor her contributions to Greenhill, Sally was recognized as a Heart of the Hill Hero, having Red 7 named after here. |

Helen and Bernard Fulton are the two most well-known founders of Greenhill School. He demonstrated his energy, versatility, and commitment to education in all guises by serving as chairman of the Addison Independent School District's school board for 10 years. In 1950, he became the founding headmaster of Greenhill School. From 1950 to 1976, Fulton served as the founding headmaster of Greenhill School, where he attracted strong teachers and secured the support of families and board members. He also pioneered the concept of open-space education and the developmental primer program in the Southwest and proved that his vision of independent co-education represented the wave of the future for the region. When he retired from Greenhill, he was recognized for his unwavering commitment to his vision and for his incessant drive to improve, never allowing the school to rest on its laurels despite its growth (from 62 to 1,002 students) and its solid position as the top coeducational in-dependent school in the area. |

Helen and Bernard Fulton are the two most well-known founders of Greenhill School. Described by Estelle Dickens as a “behind the scenes person,” Helen poured herself into the monumental task of carving out a dream from the impossible hardscrabble of the North Texas prairie. From bookkeeping to answering phones to making lunches to substitute work to sewing totebags, no task was too menial for her. Though not a trained teacher, Fulton was a keen observer of children and a tireless researcher of educational methods, and it was her initiative that brought the Cuisenaire Rods and the Orton-Gillingham reading program, among other ideas, to Greenhill. She also organized and led the annual Greenhill Summer Studies Abroad Program, a humanities-based summer travel and study experience for Upper School students. But perhaps her overarching achievement lay in her creation of a carpool system that spanned the city and provided the vital means for getting students to and from Greenhill during the early years. Quite simply, without her transportation orchestration – and her daily driving rounds – there would not have been students in the school. |

Molly Fulton Seeligson, daughter of founders Helen and Bernard Fulton, was one of the original 62 Greenhill students. As a student, she was deeply involved in the Greenhill community – she served as head cheerleader, Homecoming queen, and joined myriad clubs, including riding club, bridge club, glee club, student council, and even the youth council for traffic safety. She earned multiple accolades during her time as a student including the Ronnie Freeman award, DeLay Service to Greenhill award, the Fulton award, and Valedictorian. After Greenhill, she followed in her parents’ footsteps with a career in education. She led The Clear Spring School in Eureka Springs, Arkansas, served as Head of School at the Fulton School, and held the role of Director of The Eugene McDermott Scholars Program at the University of Texas at Dallas. Through the years, she maintained a strong relationship with Greenhill, volunteering while her son attended the School and serving on the Board of Trustees. In recognition of her longstanding commitment to the School, the Board unanimously voted to bestow her with the unique honor of Life Trustee in May 2015. A few weeks later, she received the Distinguished Alumna Award from the Greenhill Alumni Association. |

Lavonda Monk joined the Greenhill community in 1965. She began her career as a bus driver, picking up kids from all over Dallas in the morning and dropping them back at their homes every afternoon. Not long after her arrival, Monk was asked to help out in the Business Office between her morning and evening drives. When Greenhill eliminated its bus service, Monk took over the bookstore operations. She had a genuine interest in students and alumni and always remembered everyone. In 1990, she was named an Honorary Alumna of Greenhill School. To honor her contributions to Greenhill, Monk was recognized as a Heart of the Hill Hero, having Blue 4 named after her. |
