MIA was founded based on the principles of providing excellent, specialized investigative services based on years of experience gained in the public and private sectors. We have performed all levels of background investigations for a law enforcement agency in Los Angeles, California for eight years. The efforts of our investigative accounting team have resulted in millions of dollars of savings for our clients. We have accomplished this through strengthening of internal controls, the review and verification of assets and the detection of fraud, embezzlement, theft and white collar crime. Our undercover operations have secured restitution for our clients and assisted law enforcement in prosecution of criminals.

Brent Grubbs, Principal/Owner, has over 25 years of accounting and investigative experience. He has held positions as a Regional Audit Manager, Financial Manager and Assistant Treasurer in a Fortune 100 corporation. During this time, he supervised operational and financial audits for North & South American operations and created and chaired a Special Projects section which included fraud investigations, inventory losses and acquisition reviews. In the private sector, he has created a unique business that blends accounting and financial expertise with natural investigative skills. He is also a recognized expert witness in the Los Angeles County Superior Court system as a Forensic Accountant. His testimony has resulted in clients obtaining judgments and favorable rulings in every case.


Mr. Grubbs is a member of the Association of Certified Fraud Examiners (ACFE).

MIA's support staff includes experienced accountants, former controllers, special investigators and former law enforcement officers. This, we feel, offers us a wide variety of services without compromising quality, quantity and attention to the client. We have access to numerous information sources which facilitate our investigations and provide immediate responses. Further, our contacts developed over the years with law enforcement, government agencies and the legal community only enhance our ability to give expert support to our clients. We provide service without compromise.


MIA was created with the needs of the client in mind. After successfully starting and operating an investigative agency on the west coast (Southern California Intelligence Agency), Midwest Intelligence Agency was a natural and carefully evaluated expansion of the principles and methods which have proven successful and time tested. MIA’s  presence in the Heartland of America will provide the benefit of strong experience and a proven formula for results for the client.
