Karen Winterhalter

Our driven and determined Director, Karen, has taken a step back from leading the agency but continues to provide strategic counsel to our clients, while looking for opportunities to expand the business globally.


Having established Onyx Health in 2003 and been instrumental in supporting our clients expand their brands and services, Karen is now doing the same for Onyx Health. For those of you who know her, that strategic brain never stops, so when needed, she is there to support clients.

Karen’s experience covers a diversity of areas including opinion leader contact at the highest level, market access, advocacy development, social marketing, digital communications, health policy, medical education, corporate communications, issues and crisis management, media relations and strategic management of communications programmes.

One of Karen’s favourite weekend pastimes is lying on a beach doing absolutely nothing. She is now doing that (semi) permanently in Spain, and rumour has it she has swapped her killer heeled Jimmy Choo’s for Valentino flip flops.
