Stannard, reverting to her maiden name from Owen, resigned from SHL in 2003 after a period of maternity leave to join Packer Forbes Communications (PRWeek, 23 January 2004).
She has now rejoined SHL - part of the Shire Health Group, at which she spent seven years - after leaving PFC last month.
PFC managing director Alexa Forbes said: 'She leaves with our very best wishes. We'll continue to benefit from the experience she brought to Packer Forbes.'
Stannard reports to SHL managing director Matt de Gruchy on a four-strong management team that also includes Sian Boisseau and Ali Wright. She is heading UK work for Pfizer's Celebrex, plus UK remits for Merck Sharp & Dohme.
De Gruchy described Stannard as 'effectively replacing' Lucie Harper, who is joining Weber Shandwick (PRWeek, 17 June).
