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.

Tiffany Chamberlain is a current MFA candidate studying Studio Art at American University in Washington, D.C. Tiffany received her Bachelors of Arts at Rowan University in Glassboro, New Jersey where she specialized in Philosophy, Religion and Sociology. Since the completion of her undergraduate studies she has worked with the State of New Jersey’s Treasury and has gained experience in K-12 education. Tiffany is an emerging artist who has become fascinated with the DMV area, often learning new facets of culture and community in the ordinary places. She has participated in local New Jersey exhibitions and currently shows at the Tilghman Gallery in Atlantic City, NJ. When not admiring culture and community stateside, Tiffany dedicate time during the year to do international mission work. In her travels she has come to the realization that she has absolutely fallen in love with the country of Cuba, primarily avoiding all the main attractions of tourist life and ready to shamelessly practice her Spanish.
