It seems that there is enough evidence to support the neighborhood's existence. Despite its odd pronunciation, which is meant to rhyme with Noe Valley (which we question, since PV has seemingly seceded from its mother 'hood), Pierre Valley does seem to have a personality all its own. According to its website, Pierre Valley has its own monthly neighborhood grills. (They are currently seeking a new grill master.) What fun! It is also home to Mitchell's Ice Cream, starch-heavy Pomelo, and Sister Act's St. Paul's Catholic Church.
