Who we are

Karen Winterhalter

Driven by an innate passion and desire to deliver communications programmes that really make a difference to healthcare, I founded Onyx Health in 2002.

I have over 25 years experience within the global pharmaceutical industry and healthcare communications. I have developed a wide number of programmes that have brought about real change and improvements healthcare. My experience covers a diversity of areas including opinion leader contact at the highest level, market access, advocacy development, social marketing, health policy, issues and crisis management, media relations and strategic management of communications programmes. I have also been at the forefront of developing digital marketing within health communications.

Individually we excel, together we exceed

I have held several senior positioning within global communications companies. I have previously been the Managing Director of EMEA Healthcare at Burson Marsteller and European Director of Healthcare at Weber Shandwick. Within both roles I was responsible for the strategic growth and development of the business and working directly with clients to address the ever changing complex communications within healthcare.

In my spare time I love running, buying shoes, drinking red wine and lying on a beach doing absolutely nothing.
