retiring faculty & staff

We are deeply grateful to our retiring faculty and staff members for their years of service to our school.

KAREN REDDIN 2 Years of Service

Karen Reddin has retired after two years of service as an assistant nurse. Reddin served for many years as the Director of Health Services at Hockaday and is the parent of Danny ’07. When COVID-19 emerged, Reddin was asked by her longtime friend and St. Mark’s school nurse Julie Doerge to help the School navigate the pandemic. From 2020–2022, she helped manage all aspects of the School’s COVID-19 response, including patient care, screenings and policy development.

ANN DILDAY

11 Years of Service

Ann Dilday has retired after more than a decade of exemplary service as the heartbeat of the Middle School office. Arriving at the School in 2011, she guided Marksmen with grace and care, always with a smile and helpful touch. For Dilday, there was never a task too big or too small. She’s choreographed final assemblies, organized events, chaperoned choir trips, hosted guests and has always been a go-to colleague. A Superior Staff Award winner, Dilday earned the respect of boys, parents and colleagues with her boundless energy, her thoughtfulness and her commitment to serving others.

DOUG RUMMEL 24 Years of Service

After nearly a quarter-century in the Science Department, Doug Rummel has stepped away from full-time teaching to spend more time with his family. A devoted and gifted educator, Rummel was appointed to the Founders’ Master Teaching Chair in 2016. Rummel has a passion for engineering and has inspired his students to appreciate the value of solving complex problems through his popular Information Engineering class. His prowess in the classroom has earned him the admiration and respect of generations of Marksmen. Although he has stepped down from a full-time role, Rummel plans to remain engaged on campus and continue teaching on a more limited basis.

LUPE MURATALLA

27 Years of Service

Loyal campus maintainer Lupe Muratalla has retired after 27 years of service to the School. Working around campus, Muratalla put effort into every small detail, making sure the grounds of 10600 Preston Road stayed green, clean and vibrant. He was known for his sociable personality — along with his tools, he always had a joke in his back pocket. Muratalla received the Superior Staff Award in 2007.

MARY ANN LIVENGOOD

50 Years of Service

Mary Ann Livengood is retiring after a remarkable 50-year career at the School. For five decades, she inspired boys to raise their voices in song, to create, dance and perform, and most important, to develop into good, caring, responsible men. Alongside her late husband Jim, she helped grow the St. Mark’s Choir into one of the most renowned programs in the world. She touched the lives of thousands of Marksmen, helped St. Mark’s establish and lead the international choir tour, supported chapel experiences, guided Lower School musicals and much more. Livengood's impact on the School has been indelible and will be missed.
