Shareholder - Sioux City, IA
Corey Moss, CPA
Experience
Corey began his career with Williams & Company in 2010 as a staff accountant, bringing with him a passion for practical problem-solving and a strong foundation in accounting. Over the years, he has built a successful career serving a wide range of clients, particularly small businesses, farms, and individual taxpayers. Corey’s commitment to client success, combined with his approachable style and technical expertise, led to his promotion to shareholder.
Though he initially entered college as an engineering major, Corey quickly realized it wasn’t the right path. Remembering a high school accounting class he had enjoyed, he made the switch—and found a lasting fit in the accounting profession. Today, Corey’s work is rooted in building relationships, delivering strategic financial guidance, and helping clients navigate everything from taxes to long-term planning.
One of the things Corey values most about Williams & Company is the people—the supportive network of staff and leadership—and the unique balance of being a large, reputable firm that still feels like a close-knit team.
