Since 1997, we have had a mission.
That mission is your clinical trial.

Odette and Michael are true pioneers in clinical development.  In 1997, they brought together large scale international project management and regional clinical expertise together to address an underserved group of Sponsors. In doing so, they created PSNResearch – a team custom-fit piece by piece to outperform mega-CROs; building relationships in dozens of countries and localities worldwide.
