Charlie Carter, SE, PE, PhD, president of AISC, said, “Danielle’s new title reflects that the NSBA division of AISC is now also fully integrated as a department of AISC. We already are enjoying the benefits of this unification, with sharing of marketing, legislative, and technical ideas and resources, and increased collaboration among our departments. Danielle will further grow these capabilities and activities and continue to build the NSBA brand that has come to be so well recognized in the bridge community.”

Cross, who will be retiring in July of 2018, has served as AISC’s vice president of market development for nearly 15 years, and also led its finance department for eight years.
