Lena Zhang,  AIA , LEED AP, is the founding Principal of Z Studio Architects in San Francisco over 15 years ago, after a long career with a number of high design firms specializing in large scale projects around the world.  With a background in designing and managing large award-winning projects, Lena was motivated to start a practice focused on client care, environmental sensitivity and exceptional design. While Lena's aesthetic leanings are toward modernism in design, all of her work is grounded in a knowledge and respect for both classical architecture and site specific context.  Large and small projects are executed with the same attention to listening to the client's needs, and executing with a limitless attention to detail.  All projects have a foundation in the natural environment, and Lena is always testing and applying the best practices for sustainable design to her work.  With an M.Arch. from New York State University, Buffalo, and a B.S. in Building Structural Engineering from Tongji University in Shanghai, Lena’s combined knowledge in both fields has bolstered her efforts on many challenging projects.
