Support for an Important Cause

October 24, 2016

We enjoy supporting those causes that matter to our agency partners. Recently, we sponsored a hole at a charity golf tournament to benefit Part of the Solution. Our agency partners at Alliant are very involved with this Bronx-based organization, which focusses on fighting hunger and poverty in the local community. We are happy to see our partners enjoying a day on the golf course for a good cause!
