She has worked for a variety of firms  from Pittsburgh to San Francisco,  and is licensed in the states of Arizona, California, and Oregon.

Taz 's interest in urban design issues and the impacts of architecture on society led her on a journey of discovery taking her through Portland and San Francisco, and now back to her home town of Phoenix.  Her deepest interest lies in how the built environment – cities, buildings, and spaces – can ultimately be used to cultivate community and human connection.
