Why Galen?

Galen of Pergamum was a prominent physician and philosopher during the Roman Empire. One of the most accomplished researchers of his time, he made significant contributions to our early understanding of pharmacology, anatomy, and neurology. 

Galen Diligence incorporates this ambitious commitment to research in our work as advisors in an emerging industry.
