Three Arch Partners

Three Arch Partners was formed in 1993 to provide young companies with access to relevant clinical and business resources, as well as capital. Three Arch has helped create, build and fund more than 100 important new healthcare companies. These companies have often become the clinical and market leaders in their respective fields, and have generated strong returns. The fund focuses on opportunities in medical devices and healthcare services, and less frequently in biotechnology.
