About Gill Insurance

The Gill agencies are a trio of locally and family-owned, independent insurance agencies. From our roots in the South Carolina Piedmont, we have now expanded to serve the Lowcountry.

About Us

We have been serving our neighbors across South Carolina since we were established in 1961 in Rock Hill, SC.  Since then, three generations of Gills have combined to work on behalf of their communities to provide them the most comprehensive insurance coverage at the best prices available. The Gill agencies now span from Rock Hill to Fort Mill to Charleston. Our Charleston branch office opened in 2018 with an eye on specifically serving the residents of the Lowcountry.

Benefits of Working with an Independent Agent


Independent agents sell policies provided by multiple insurance companies, offering you more choices of coverage at multiple price quotes. Let our agents do the shopping for you and find the right blend of price, coverage, and service for your unique situation.


We work for you, not the insurance company. Come directly to us, the same person who you bought the policy from, for servicing, billing, and claims issues, and we will act on your behalf. 


We take the time to listen to you and understand your individual needs. We know it’s not just about finding a price you can afford; it’s also about making certain you are properly covered, so you can have peace of mind that you will be taken care of if something unfortunate happens.


Local knowledge. Personal attention. Community oriented.
