A little more about GCO

GCO is a professional conference organiser, dedicated to mutually beneficial partnerships within the life sciences industry. GCO, successful for over 25 years, operates with a global footprint. 

We are proud of our passionate and highly skilled staff (20+ nationalities) and being ‘multi-culture capable’ of getting the job done. 

GCO maximises value creation for her clients by operating fully transparent. We manage expectations and tailor each program to support your objectives.

Strong project management and solid financial control lead to full transparency, meaning cutting out all hidden costs including VAT, commission, and kickbacks and reducing clients’ internal costs by working seamlessly integrated with their SOPs and reporting requirements.

Pharmaceutical compliance control requirements and mandatory reporting (e.g. Sunshine Act, EFPIA, and country specific legislation) are fully supported by GCO.
