Sean Casey is an experienced entrepreneur, technology executive, board member, and advisor. He is currently the Head of Product for divvyDOSE, an early-stage tech-enabled pharmacy, where he brings his technology and leadership skills to help scale the business. Sean’s life as an entrepreneur started in high school when he launched a web site for the local music scene in Chicago. In 2001 Sean went on to attend University of Illinois at Chicago for Computer Engineering and in his freshman year co-founded All Information Services (AIS), a boot-strapped technology consulting company serving small businesses.
