"Preservation is not only about restoring historic monuments, but also about recycling durable buildings; even contemporary structures can have their exterior envelope performance enhanced. The character of our urban areas, landscape and society is defined by what we save, giving us a sense of place as well as the continuity of history. At the same time, preservation is about managing change. Historic buildings are the backdrop for the new structures we create."

"I marvel at the transformative power of the built environment, its effect on us and how it motivates us to strive for design excellence for our communities. Of special interest to me as an architect is that place where technology and artistry intersect, where each is essential to the other and where we can apply this synergy to enhance people's lives."
