Biotechnology leader CSL Behring expands its Philadelphia-region footprint.

CSL Behring's new location at 500 N. Gulph Rd. in King of Prussia, Pennsylvania

CSL Behring’s remarkable trajectory has transformed what was once a laboratory owned by the Australian government into the world’s fifth-largest biotechnology company with a focus on patients living with rare diseases.

Earlier this month it moved several hundred employees into a newly-renovated office building that marks a significant expansion of its presence in the area.
