The BGS, the body for doctors who specialise in treating over-65s, has never previously used a PR agency, and is using Onyx to undertake ‘an external scoping exercise'.
The Whitehall-based outfit is working on a project basis, advising on how the BGS can campaign for improved medical care.
Separately, eight-strong Onyx this month hired Jane Wrenn as a senior associate.
Wrenn's most recent role was at Weber Shandwick, where she worked for five years. At Onyx she is working on the three-year-old agency's accounts with Teva/Lundbeck (UK account for Parkinson's disease product Azilect) and Cephalon (UK account for breakthrough cancer pain product Actiq). She also has new-business responsibilities.
She reports to partners Karen Winterhalter and Penelope Wright. Winterhalter, Wright and Wrenn all previously worked together at Weber Shandwick.
