Ann Caddell, Marketing Consultant
Ann is a technical writer, team lead, and project manager with over 20 years experience in the telecom, financial, and defense industries. She sees her function not just as a writer but as a translator, learning complex technical concepts and turning them into usable, plain English explanations and instructions for non-technical users. In this way, she helps to “bridge the gap” between the high-tech software developers and IT experts and the customers and end users who rely on their products and services.
Ann is excited to be working on HOS’s marketing communications, including website development, social media, direct marketing, and community outreach.
