What Sanger & Altgelt does

Sanger & Altgelt is a privately held, San Antonio-based independent insurance agency founded in 1900, operating as a subsidiary of Jefferson Bank following a 2011 merger. The firm distributes personal, commercial, and specialty insurance products through 70+ carrier partnerships including AIG, Chubb, The Hartford, Liberty Mutual, Travelers, Zurich, and Lloyd's of London, generating revenue through carrier commissions on policy placement and renewal. Its product portfolio spans personal lines (homeowner & umbrella, automotive, life, personal cyber, travel risk, farm & ranch), commercial lines (property & casualty, business cyber, employee benefits, surety bonds, professional liability, loss control), and a deep specialty vertical practice including energy and offshore oilfield coverage (nearly $2 billion in offshore asset capacity), commercial real estate, coastal properties, aviation, sports & entertainment, contractors, wineries and breweries, historical buildings, captives, tech startups, museums, and international exposures.

The agency operates a consultative, advisor-led sales model with a staff of approximately 16, led by CEO Mac Altgelt and President Heather Haynes, who together with CFO/COO David Smith oversee a multi-generational family-controlled firm now in its fourth generation of Altgelt family leadership. In 2023, the firm relocated to Jefferson Bank's corporate offices at 1900 Broadway, deepening distribution leverage with the parent bank. Underlying technology consists of standard policy management and CRM systems; no proprietary platform, API, mobile application, or AI/ML capability is disclosed. Customers include high-net-worth individuals, families requiring multi-generational coverage, small and mid-sized businesses, and specialized commercial accounts across South Texas and the Gulf Coast — including a publicly disclosed anchor relationship with Jefferson Bank itself.
