On Call International

On Call International is a private travel risk management and global emergency assistance company that provides 24/7 medical, security, and travel support for organizations and travelers worldwide. Founded in 1995, the company serves academic institutions, non-profits, corporations, insurers, and affinity partners with customized programs that combine emergency response, medical evacuation coordination, travel assistance, security support, and risk-prevention services. The business is healthcare-adjacent rather than a drug developer, with its core offerings centered on operational support, crisis response, and traveler safety rather than therapeutics. On Call International operates as part of the Tokio Marine HCC group of companies and maintains a centralized Global Response Center in Salem, New Hampshire, with additional presence in Indianapolis and global offices in the U.K., Asia, and Australia. Its services are fully commercialized and used to support millions of travelers and their sponsoring organizations.
