We had a great time at one of our favorite annual events last Monday. Every Childs Hope is an incredible organization helping at risk children in our community. We have been proud to have them as a client for many years. And we always have fun slinging margarita's on the golf course at their annual golf tourney raising funds to support their mission. Great weather, great people, and a great all around event, all for the ECH kids!!
