The contract research organisation (CRO) says the move will help to establish a recruitment base in the area as well as building client relationships in the area.
Barry Simms, Chiltern’s country manager, North America, said: “Chiltern continues to look for opportunities to increase our strategic footprint and we are very excited about our expansion to the greater Chicago area.
“Our new office is well situated to support our efforts to recruit top-notch staff and be strategically near our clients.”
The new comes just two months after the company established a similar enterprise in Israel.
