Disability Insurance Services operates a national wholesale brokerage from 4444 Zion Avenue Suite B in Allied Gardens, San Diego, connecting insurance agents and financial advisors across the United States with individual disability income (IDI) products from major carriers since the firm's founding in 1997. The 92120 headquarters employs a team of approximately 40 staff alongside regional representatives in Baltimore, Dallas, Kansas City, Phoenix, New York, New Jersey, and New England, generating annual revenue exceeding $7 million through its broker-support model. The product portfolio spans individual disability insurance, business overhead expense coverage, disability buy-sell agreements, key-person disability, retirement-plan disability, bank-loan disability, impaired-risk underwriting, critical illness insurance, multi-life disability, and simplified-issue programs. Financial advisors building comprehensive wealth-management plans integrate disability-income protection as a foundational layer, and San Diego-based advisory firms including Clutinger Williams and Verhoye in Del Cerro represent the type of planning practice that routes DI cases through wholesale brokerages for carrier access and underwriting expertise. Broker support services go beyond quoting to include case design, underwriting advocacy, carrier selection based on occupational classification and medical history, and sales coaching through scripts, playbooks, and real-time guidance from the DIS producing team. The firm's approach, which it calls "DI Done Right," reflects a positioning built on carrier-neutral case analysis where the brokerage matches each applicant's occupation class, income documentation, and health profile to the carrier whose contract language and claims-payment history best fit that specific risk. Impaired-risk disability underwriting serves applicants whose medical histories, hazardous occupations, or prior claims make them difficult to place through standard channels, and the firm's carrier relationships include surplus and specialty markets that write policies traditional brokerages cannot access. Business consultancies advising clients on partnership agreements and succession planning coordinate with DIS on the disability buy-sell structures that fund ownership-transfer provisions when a partner becomes disabled, a product category that firms including Shammam Consulting Services in Allied Gardens encounter in their advisory work. The Zion Avenue office sits in Allied Gardens' commercial corridor near Kaiser Permanente Zion, and the neighborhood's position between the 8 freeway and Waring Road business district provides the firm's national operations team with residential-area office space removed from downtown's commercial rents. Free downloadable resources on the firm's website include DI sales scripts, the Beginner's Guide to Disability Insurance infographic, an Income Options Worksheet, and a Broker Opportunity Kit designed to help agents incorporate disability products into their existing book of business.
