Audit Assurance from Michigan's Top CPA & Business Consulting Firm

The benefits of audit and assurance services are numerous. Audits can improve an organization’s efficiency and profitability by helping management better understand their own financial reporting systems. Risks in the organization are well-studied and controls are evaluated.

Yeo & Yeo’s experienced audit and assurance CPAs help you through the audit process and offer valuable insights. They stay ahead of the financial and compliance issues that impact your industry, help you through the complexities of reporting requirements and recommend effective internal controls.

What is important to me about Yeo & Yeo is their expertise and their accessibility. One of the most important decisions our board of directors made when I became CEO eight years ago was to retain Yeo & Yeo as our auditing partner. I stay in contact with our CPA year-round for advice and problem-solving. I make better decisions on behalf of the Youth Protection Council because of her expertise and support. Our agency is a bit complex with 16 grants braided together to keep services in place. Providing the annual audited financial statements to our funders bound with the Yeo & Yeo name carries significant weight.

Very professional and easy to work with. Yeo & Yeo has a true understanding of our business.

Liz Director, Finance


Our firm has used Yeo & Yeo to conduct our annual audit and single audit for many years. They have always been organized, thorough, and supportive. The checklists and engagement information they provide up front assist us in properly preparing for the audit and facilitate the process greatly. While on site, the auditors are efficient, professional, and helpful with recommendations for improving systems and processes. Following the audit, their presentation to our board is critically important from the governance perspective.

Jody CFO


I have worked with Yeo & Yeo for the last four years, and I am very appreciative of the relationship we have established. While I understand the need for them to maintain their independent relationship for our audit, I truly feel like we operate as a partnership or team. If I have a question throughout the year, I never hesitate to reach out and run something by them.

Jamie Director of Fiscal Services


I have worked with Yeo & Yeo as external auditors in three different school districts over the last 15 years. In addition to delivering stellar customer service in the auditing role, they serve as public school accounting experts—offering professional development and guidance to school districts across Michigan. We rely on advice and knowledge from Yeo & Yeo’s leading authorities in the accounting field.
