Horizon is a global biotechnology company focused on the discovery, development and commercialization of medicines that address critical needs for people impacted by rare, autoimmune and severe inflammatory diseases. 

Our pipeline is purposeful: We apply scientific expertise and courage to bring clinically meaningful therapies to patients. We believe science and compassion must work together to transform lives. Our mission is personal. Many of us at Horizon, including CEO Tim Walbert, are patients, know a patient or have been impacted by a patient story.

Horizon's global headquarters is in Dublin, and its U.S. headquarters is in Deerfield, Ill. The Company also has offices in Chicago; South San Francisco; Washington, D.C.; Gaithersburg and Rockville, Md., and Mannheim, Germany, as well as a growing presence in Japan.
