What do they say about our services as a CRO? 

We receive many emails with problems opportunities for improvement.

But we also receive many emails congratulating us for our work. Like this one from Noa, a Project manager who wrote to our PM and CRAs about a phase III study for the treatment of children growth hormone deficiency; a study in which you can feel the special love and dedication of the entire investigator team throughout 5 years working side by side. A study we are closing today after a handover and a pandemic.

I would like to take this opportunity to personally thank you for all the hard work and diligent effort you have put into completing this study.  

Your dedication to work, professionalism and caring really shows

You were able to complete all tasks and close all sites according to our original plan which was intensive and challenging although it was during the holiday season, and all the obstacles around that, you did it! 

It was a real pleasure working with you and a great experience from my end 

I hope that our ways will be crossed sometime in the future and we will work together once again.

Thank you and Best regards.
