Maura M. Brush
President & CEO
Maura began her career at Old Westbury Gardens as an intern in 1999. She joined the staff in 2000, shortly after earning her degree in Horticulture from the University of Maine, and was appointed Director of Horticulture in 2007. During her tenure many projects have been completed including a complete tree inventory, the commission of a Cultural Landscape Report, and the restoration of the South Allee. Having begun her career as an intern, Maura is very involved with the Horticultural Internship Program which has grown from one three-month intern to five interns with placements of six to eighteen months each.
Maura has always had a passion for Horticulture but through her work at Old Westbury Gardens, she has developed a particular focus on historic gardens and cultural landscapes. “A garden is never finished” says Maura. “There is always something to be planted, pruned, or weeded and it’s easy to get caught up in the day-to-day tasks. But, always, there is a larger goal here and that is to make each visitor to our gardens feel as if they are guests of Margarita and Jay Phipps.”
In November 2023, Maura was named President & CEO of Old Westbury Gardens.
Lorraine Gilligan

Lorraine has been Director of Preservation since 2008. Prior to her appointment, she was Executive Director of Planting Fields Foundation.

She has worked with conservators and contractors and has successfully secured funding for many projects. She is a graduate of the Attingham Summer School and has attended the Victorian Society study programs in London and Newport. She holds undergraduate and graduate degrees from Binghamton University and the University of Chicago, respectively.
