Pia was a publicist who Kelly Taylor hired to boost the business of Now Wear This, the clothing store which Donna Martin owned and operated. She paid most of the guests to be there and when Donna found out, she fought with Kelly and fired Pia. However, Pia loved the drama and felt it added to the business.
They later hired her back to publicize their reopening after the shooting death of Joe Patch within the store to push her men's designs. Although Pia's plans didn't work out as planned when all of her models got stuck in traffic, the gang stepped in and saved the day.
She later recruited Kelly to come work for her business, but Kelly initially declined. Later, however, Kelly went to work with Pia after she changed PR firms. However, after she and Pia couldn't agree on the purpose of public relations, Kelly quit her firm.
