Anh joined AGA after she received a BARCH from California College of the Arts here in San Francisco. To thoroughly understand the practice world,  she worked voluntarily with SF Planning Department and CCA Design Build Lab while studying at CCA. Anh is a creative designer with a passion for art in all its form - especially photography - where she can express dramatic landscape (nature and urban) through the artistic lens. If she isn't busy with architecture works, she can probably be found hiking across the wilderness.

As the daughter of a contractor from small-town Pennsylvania, Tiffany was exposed at an early age to construction sites and developed an affinity for fine details and traditional design.  After graduating from Pratt Institute in New York with a Bachelor of Fine Arts in Interior Architecture, she apprenticed for eight years under an architect specializing in custom residential design.  Tiffany's untiring dedication and adventurous spirit resulted in a promotion to the San Francisco office.  She enjoys escaping the city to backpack, rock climb, and canyoneer in the desert.  Autocorrect is the bane of her existence.
