About Us

Alteris is a member of Argo Group International Holdings Ltd, which is a specialty underwriter of insurance and reinsurance products. This ownership structure melds the resources and global reach of a publicly traded company with the entrepreneurial dynamics of a niche-oriented agency. The latter point is essential as effective trading relationships are personalized, tenured, and principal-based.

Our cross-functional teams are designed to maximize responsiveness and accountability. We are committed to meeting expectations and providing sustainable value to our brokers, clients, and carrier partners. Alteris is headquartered in San Francisco, with offices in San Antonio and Seattle. We invite you to tour our website and contact us with any questions.
