What Our Clients Say About Us

DGC has a culture where the people genuinely want to do what is in the best interest of the client. This contributes to their flexibility in terms of approach, and is invaluable.  This is something you don’t find at a Big 4 firm.

Ken Manning Chief Operating Officer Curaspan Health Group, Inc.

The speed in which the financial statements were produced and the tight time frame which DGC completed the audit was refreshing. DGC had a comprehensive understanding of our business which minimized my need to respond to questions. The approach was collaborative and flexible.
