Supported by our talented team, I see tremendous opportunity to expand our global presence, deepen therapeutic expertise, and leverage advanced technologies to help our customers bring better treatments to patients worldwide,” said Bassem Saleh.

In addition, his medical background aligns perfectly with our deep scientific roots, further strengthening our commitment to advancing clinical research worldwide with our clients.”
