Ethics and Fraud Speaker

Home: Welcome


Nathan's Story

Nathan holds a B.A. in Accounting from Gustavus Adolphus College and was a licensed CPA from 2002-2010. He has over 13 years of public accounting experience and ten years of corporate accounting experience with a focus on financial reporting, cash processing, and accounting controls.

After the reinsurance company Nathan worked for was purchased by ING for $6 billion, he played a key role in transitioning its operations onto ING’s enterprise resource planning system. Enabled by lax controls and unchecked authority to distribute funds, Nathan began embezzling money to pay off personal debt. What started as a $1,100 check to a credit card, spiraled into an $8.5 million fraud over the next four years. It was only a co-worker’s suspicions that brought the fraud to an end. After being caught, he pleaded guilty and was sentenced to 97 months in federal prison. He was released in September of 2014.

Since his release from prison in 2014 Nathan has become a sought-after speaker for Compliance and Ethics presentations for diverse and notable organizations across the United States, giving more than 200 presentations for various audiences including the FBI, FDIC, FFIEC, the Federal Reserve Bank, Best Buy, General Mills, and Nationwide Insurance to name a few. He also speaks frequently for many organizations including the IIA, ACFE, IMA, HFMA, ISACA, ACAMS and state CPA societies.

Speaking and training are not the only avenues Nathan has pursued to bring fraud and ethics awareness to all industries.  He also co-authored "Lessons From An $8 Million Fraud" in the Journal of Accountancy which won the prestigious Lawler Award as the article of the year for 2015.

"Mr. Mueller recounts his experience through a presentation that addresses fraud, lack of risk management and internal control, opportunity, and human flaw. The presentation is beneficial for all industries and companies. I have attended many seminars and trainings over my 13+ years as an internal auditor and this was by far the most enlightening of all!"
