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 approaches each project as an architect and a structural engineer. 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.
Adrienne Agee
Assistant, BA, Registered Tax Preparer
Adrienne joined the team in July 2023 as the bookkeeper, payroll specialist and assistant. A native of Rochester, New York (the home of Wegmans!), she came to Charlottesville to study at the University of Virginia in 1992. She originally intended to stay just long enough to complete her degree, but the traffic in the D.C. area combined with the stunning beauty of the Charlottesville area were enough to convince her to stay here.
She brings a wealth of experience as a former customer service manager and tax preparer to the firm, a skill set she accidentally stumbled upon at the suggestion of a relative. She was surprised to learn that she actually enjoys preparing taxes for others, especially because she can help demystify them and make the process easier for people. She's excited to apply this knowledge and experience to her role at Gehrung+Graham.
When she's not working as an assistant or demystifying taxes, you can find her substitute teaching for Albemarle County schools, serving as a girl scout leader, or running errands (a seemingly never ending task). Her two daughters, Simone and Evan, keep her on the go!
Jeffrey Justice
Energy Engineer
Jeffrey received a Bachelor of Science in Civil & Environmental Engineering from the University of Virginia, where he studied the interaction of natural and technical systems with a focus on human-induced climate change. Over the past decade, he has worked on energy efficiency and resource conservation projects in buildings and infrastructure with UVA's Office for Sustainability, the Local Energy Alliance Program, and rooftop solar firm AltEnergy Inc. He sees building science as a key opportunity to reduce energy use and steward the environment that our buildings inhabit. He helped initiate the Solar Installer Workforce Services program at Piedmont VA Community College, and has designed and built off-grid solar energy systems for the Virginia Coast Reserve Long Term Ecological Research lab. He is a board member of the Charlottesville Tool Library which provides community access to an extensive library of general and specialized tools. Jeffrey restores vintage motorcycles, sails in the Chesapeake Bay, and plays violin.
ALUMNI & FORMER TEAM MEMBERS
Jaime Justice
Assistant
Jaime Justice graduated from the University of Virginia in 2017. As a student, her interdisciplinary work focused on architectural and environmental history, specifically the dynamic relationships between the social and the ecological as expressed in landscape design. Her work with Gehrung + Graham 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.
