Barbara Gehrung

Dipl.-Ing. Arch., AIA Int. Assoc., CPHC

A native of Germany, Barbara developed a passion for architecture, design and sustainability growing up, while the green building movement there grew from exotic to main stream. First as architecture student, then as faculty at TU Darmstadt, she focused on energy-efficient building design. Following an internship at the Center for Building Performance and Diagnostics at Carnegie Mellon University, she initiated and led Germany’s first participation in the U.S. Department of Energy’s Solar Decathlon competition in 2007.

Mark Graham

Registered Architect, AIA, LEED AP BD+C, CPHC

Mark C. Graham studied both architecture and structural engineering at the graduate level. In 1997, Mark received a Master of Architecture from Harvard University after completing a Master of Science in Civil & Environmental Engineering at the Massachusetts Institute of Technology in 1994, and a Bachelor of Arts in Engineering Sciences at Dartmouth College in 1991. Accepted into the Eidgenößische Technische Hochschule (ETH) Exchange Program, Mark studied in Zurich, Switzerland, while working at the architectural firm Burkhalter + Sumi. Upon graduation, Mark continued his professional career with a unique grasp on both the technical and creative aspects of design. He has practiced at preeminent firms such as William McDonough + Partners and HO+K’s Science & Technology Group, where he shaped projects to the highest level of environmental performance and design quality.

Alisha Savage

Registered Architect

Alisha joined Gehrung + Graham in 2018. She received her Bachelor of Science in Architecture in 2001 and her Master of Architecture from the University of Virginia in 2005. As a recipient of the Sarah McArthur Nix fellowship, Alisha examined the ongoing adaptation of a medieval urban fortification within Paris. Additional studies in Copenhagen, Venice and Jamaica shaped her interest in design at various scales and in a wide range of typologies. Working recently with Nelson Byrd Woltz Landscape Architects, Alisha contributed to a variety of projects from a roof garden—part of a larger, education-focused development at King's Cross in London, to a Virginia state park dedicated to the interpretation of Werowocomoco, the political center of the Powhatan chiefdom during the early 1600’s, to residential landscapes in the Bahamas and Nashville and Conservation Agriculture projects in Tennessee. Alisha taught undergraduate architecture studios at the University of Virginia, and has practiced in Charlottesville and Washington DC. Her work has been recognized through regional and national awards and appeared in several publications.

Jaime Justice


Prior to joining Gehrung + Graham as an intern in the fall of 2017, Jaime Justice graduated from the University of Virginia in May of that year with highest honors. Her undergraduate interdisciplinary work focused on architectural and environmental history, specifically the dynamic relationships between the social and the ecological as expressed in landscape design. Her thesis on this subject, entitled “Grounds of Difference: William Chambers’ Encounters with the Other in the Royal Botanic Gardens at Kew, 1758-62,” won the Stephen T. Thornton Outstanding Capstone Project Award. Her work with Barbara, Mark, and Alisha has given her an opportunity to broaden these interests by learning the technical aspects of design, and she is thrilled to work with a team of architects so committed to fostering both aesthetic excellence and environmental soundness. In addition to her role as a design apprentice, she works behind the scenes as a writer, web designer, bookkeeper, researcher, and general administrative assistant. Jaime lives in the Charlottesville area with her family.
