D R Sullivan & Company, CPA PC is not your typical CPA firm. Originally founded in January 2000 as Donna R. Sullivan, CPA PC, the firm was renamed in early 2009 as a result of a business combination with Sullivan Consulting, Mark Sullivan’s tax controversy firm founded in 1998. Mark and Donna, a husband and wife team, effected the business combination in order to streamline operations and better serve their clients.
We specialize in tax controversy issues – representing our clients before the IRS; litigation support and expert witness; and small business/shareholder accounting.
Although based in Saint Louis, Missouri, we serve clients nationwide.
Our firm and employees are also dedicated to our families and the communities in which we live. We are proud to support the following organizations and causes:
USO of Missouri
St. Louis Crisis Nursery
Our Lady’s Inn
Legal Advocates for Abused Women
Humane Society of Missouri
The schools our children attend
