Founded with purpose.
Grown through passion.
We began as a small, retail brokerage firm in 2008 dedicated solely to insuring nonprofit and human service organizations. Developing our core philosophies and practices since that time, we have grown into multiple businesses providing a range of brokerage and underwriting capabilities. As we did, we ensured that our stakeholders benefited from the expertise that niche-focused businesses deliver, while leveraging the efficiency of shared services (HR, IT and Finance) across our family of companies. In short, Signers National is the single entity providing resources and counsel to the whole of this system.
