The mural-streaked, gritty Mission District is a neighborhood that Teenage Mutant Ninja Turtles’ pizza-obsessed Michaelangelo would have happily – and hungrily -- prowled. He may not have had use for its tattoo parlors nor vegan bakeries, but the plethora of Italian joints?

For all who ascribe to this ninja’s rule that ‘forgiveness is divine, but never pay full price for late pizza,’ Mozzeria makes 16th and Guerrero a second home.

The pizza, which is flash-cooked in 60 to 90 seconds, is as punctual as it is divine. The fast-and-furious hands of the all-deaf 15-member staff use sign language just as quickly as they compose a Quattro Formaggi pizza.

The Deaf owners of San Francisco-based Mozzeria have hit the mark in deaf-friendly entrepreneurship. Five years ago, husband-and-wife team Melody and Russell Stein knew the odds of starting a business in a city with high minimum wage, taxes, and rent.

Undeterred, they forged ahead and opened Mozzeria in late 2011.
