Turns out to be a very sad story that Chris has had to quit making pizza due to really severe asthma. I say "sad," not as a customer, but I feel sad for Chris personally that he is having to step away from something he has been so passionate about.
From the Arizona Republic:
Chris Bianco no longer making pizzas
From the Slice blog, a statement from Chris:
Best wishes to Chris, I'm hoping he takes care of the most important thing -- his health.
