Once upon a time at SCI-Arc, I encountered Barbara Bestor sitting on my jury for a crit while pursuing my Masters degree in Architecture. Crits are like defending yourself against a crime that you know you have committed, and I recall that Barbara found me to be particularly guilty. Well, she may not have been enamored of my design that day, but I am quite impressed with the work shown on her website.
In her 30's, Barbara Bestor has established herself in a profession that is hard to break into at a young age, especailly as a woman in a profession (even in 2005) skewed towards men. Based upon my experience with her and what I have seen of her work, I can see how she has done it... she is tough talking and opinionated but refined, talented, knowledgeable, and skilled at producing wonderful results with small budgets.
