EXECUTIVE DIRECTOR: Holly Koons McCullough


Holly Koons McCullough is an experienced curator and arts administrator. Most recently, she served as Executive Director/Curator at the Greater Reston Arts Center, where she oversaw the administration and development of the organization, as well as six to eight changing exhibitions annually. McCullough was responsible for exhibiting nationally-recognized artists in the gallery, including Renée Stout, Joyce J. Scott, Patrick Dougherty, Shih Chieh Huang, and in 2017, Radcliffe Bailey.

Prior to relocating to Northern Virginia in 2011, she served as the Director of Collections and Exhibitions at the Telfair Museum of Art in Savannah, Georgia, where she was responsible for the care, display, and interpretation of the Telfair’s collection of nearly 5,000 works of art, as well as an ambitious schedule of twelve to sixteen changing exhibitions annually.

During her fifteen-year tenure at the Telfair, McCullough managed the curatorial department, participated in planning the Telfair’s new contemporary building, and developed and presented dozens of exhibitions. Major accomplishments included the publication of the Telfair’s first collection catalogue; the acquisition of several significant works for the collection; and the spearheading of Dutch Utopia, the Telfair’s first internationally-traveling exhibition. She holds a B.A. from the University of Georgia in English and art history, and a M.A. in art history from the University of Notre Dame.



Before coming to AAC Karyn Miller spent nearly a dozen years building relationships with the region’s emerging artists and perfecting her knowledge of DC’s contemporary arts scene. Miller served as gallery director for five years at Conner Contemporary before moving to CulturalDC’s Flashpoint Gallery, where she devoted another five years to collaborating with artists and honing her curatorial skills. Miller led several off-site public art projects at CulturalDC including Construct, a series of art installations in vacant retail spaces; Sweet, a public art project with artist Nekisha Durrett, and FREE SPACE, an installation at MLK Library by Michael Dax Iacovone and Billy Friebele. Additionally, she spearheaded CulturalDC’s marketing and communications activities. Miller has served on panels and lectured at a variety of institutions in the region and has curated and juried exhibitions at Civilian Art Projects, Orlando Museum of Art, Gettysburg College, Catholic University and Maryland Institute College of Art.

Hailing from rural Pennsylvania, Miller graduated with honors from The Catholic University of America with a Bachelor of Arts in Art History, and later received a Master of Arts in Art and Museum Studies from Georgetown University during which she completed coursework at the Sotheby’s Institute in New York. She lives in the relatively unheard-of Brightwood neighborhood in Washington, DC with her husband, Alex, and five feral cats, all of which are named after early American historical figures.
