Williams & Company is proud of our long list of clients with whom we have had the pleasure to work with over the years.  We combine the experience of a large firm with the personal attention that only a small firm can provide.  We work hard to develop long-term successful relationships with our clients.

We are committed to investing in our employees, our clients and our communities.  Through this commitment, we will continue to provide growth opportunities to our staff as well as valuable relationships with our clients.

Williams & Company PC Announces Acquisition

Williams & Company PC, one of the leading regional accounting firms in the Midwest, is pleased to announce the acquisition of the Estherville, Iowa based Nelson, Gayer, Versteeg, CPAs (NGV) accounting firm.   

The appeal of this acquisition is that both firms share the same values and core commitment to their clients.   Current NGV clients will experience relatively few changes as the entire NGV staff will be joining the Williams & Company team.  Their dedication to the success of their clients and expectation of personalized service will not change.  NGV clients will continue to benefit from their Estherville staff relationships while gaining the resources and expertise available through Williams & Company. 

Danny Dekker, currently a manager in the Williams & Company Spencer Iowa office, will be leading the Estherville location through this transition and into the future.  Danny has been with Williams & Company since June 2007.   He has extensive tax and audit experience and is looking forward to meeting and working with the clients and staff in Estherville.   Danny and his family plan to relocate to Estherville in 2019.

Williams & Company PC currently has five offices in Iowa located in Sioux City, Le Mars, Onawa, Sheldon, and Spencer and one office in Yankton, South Dakota. They are a full-service accounting and consulting firm providing traditional tax, accounting and attest services to individuals and businesses of all sizes, as well as services in the more specialized areas of government, not-for profit litigation support, business valuations, wealth management, and agriculture.
