About Us

"Ænigma" is the Latin term for a mystery or difficult puzzle. Aenigma Group is your resource to aid in solving these problems.
Aenigma is dedicated to providing superior and specialized investigative services to the legal and business communities, as well as to decision makers and select individuals.

Who Are We?

Aenigma Group was formed in order to leverage the abilities of several experienced investigators and consultants. We are a motivated team of skilled and disciplined individuals operating under the highest levels of integrity and confidentiality and dedicated to the determination of the truth and the enhancement of the safety and security of our clients.

The investigations business exists from the need and desire for information on both a precautionary and reactive basis. As the world becomes more complex, mobile and crime ridden, prudence dictates actions to minimize actual and potential danger of loss on a personal, professional and corporate level.

In our capacity as a private investigations firm, we serve as a professional problem solver for the legal, financial and corporate communities as well as select individuals. Aenigma utilizes the talent of its personnel to derive information and creative solutions that the client requires for the task at hand. Our personnel consistently produce the highest quality service within the scope and limitations of a case. Aeingma's management team works closely with our clients and investigators to ensure effective communication, appropriate action and ultimately client satisfaction.

With our broad range of education and experience, Aenigma possesses the capabilities required to perform extensive investigations and in-depth analysis. Aenigma's personnel hold degrees in Criminal Justice, Law, Psychology, Finance, and Business Administration. These talents are directed towards the company's efforts in background investigations, asset searches, public record searches, subject locations, surveillance, fraud investigations (infringement, insurance, and real-estate), civil and criminal activity. We continually search for additional trained and experienced individuals that will enhance the company's team and services.

While the majority of our clientele are Law firms and the Corporate Sector, we also do work for the select individual. It's an old saying, but it holds true: "No job is too big or too small." We've done the big jobs, like setting up surveillance at over 50 stores for a Nationwide Food Chain; and we've done the smaller jobs, like finding the phone number to an out of town TV station. And just about everything in between.
