Silver Spring


From its Silver Spring campus in Montgomery County, United Therapeutics is the first publicly-traded biotech public benefit corporation (PBC). We are committed to scientific research and discovery to help cure pulmonary arterial hypertension and create an unlimited supply of manufactured organs for transplant. 


United Therapeutics has submitted a plan - Unisphere Expansion – Biohealth Priority Campus Plan – to redevelop the site of the former Hampton Inn/Homewood Suites at 8728 Colesville Road, with an expansion of the existing Unisphere at 1000 Spring Street, to include new and relocated business functions.


Following the community meeting, United Therapeutics will complete the application process and submit to the Montgomery County Planning Department.
