Agency, not insurer
Citadel Insurance is an insurance agency, not an insurance company. Coverage is provided by the issuing insurer. All coverage is subject to underwriting approval and availability, and to the terms, conditions, limits, and exclusions of the policy as issued. Descriptions of coverage on this site are general summaries and do not modify any policy.
No coverage through this site
Coverage cannot be bound, changed, or cancelled through this website, by voicemail, or by email until confirmed in writing by a licensed agent.
Not affiliated with any state or federal program
We are not affiliated with, endorsed by, or acting on behalf of any government agency or program, including the Florida Department of Financial Services, the Florida Office of Insurance Regulation, Citizens Property Insurance Corporation, FEMA, or the National Flood Insurance Program. References to these programs are for general information. Citadel Insurance is also not affiliated with any other company that uses the name “Citadel.”
Carriers
This site does not currently display insurer names or logos. If it does in future, they will appear only to identify insurers with which Nymble Insurance holds a direct appointment, and remain the trademarks of their respective owners. The availability of any insurer depends on the agency’s appointments and each insurer’s underwriting guidelines.
Compensation
Like most independent agencies, Nymble Insurance is typically compensated by commissions paid by the insurers with which it places coverage. Commission rates can vary by insurer and product. You may ask us about our compensation at any time.
General information only
