This is what community looks like. We're proud of the Allstaters in Dallas-Fort Worth for showing up in a major way for Genesis Women's Shelter & Support. They packed hundreds of toiletry bags and hosted a food drive to help support women in need on their healing journey.

Our employees' passions become ours. This is why each Allstate employee gets PTO to volunteer their time to causes they care about.
