Our Team


Bruce T. Nilsson

Founder and CEO / Investigator / Detective

Mr. Nilsson has over 50 years’ experience in retail loss prevention upper management. He was the Senior Loss Prevention Executive in the southern region for Kmart Corporation, responsible for the operations and security for 78 to 450 units within the southern states. Mr. Nilsson developed all major loss prevention programs pertaining to internal and external theft investigations and developed all operational and loss prevention procedures. In all assignments, he had the lowest waste in his stores and held, year after year, the highest total profit average. His positive team management, investigation style, and training techniques created some of the best loss prevention professionals in the industry.


One of his major successes was building the loss prevention program into a positive proactive department for his stores. His “labor of love” with his profession was borne while assigned as an interviewer for the National Security Agency while serving in the USMC. From there, he began his law enforcement career in south Florida. His expertise developed into a leadership role as a trainer for new officers and as a firearms range instructor. He continues that role as a certified State of Georgia classroom and firearms instructor.


Mr. Nilsson’s distinguished career includes his role as a Senior Corporate Internal Investigator with Bugle Boy, assigned to the eastern half of the United States. Later, he was a Senior Corporate Consultant/Investigator/Trainer and the Lead Forensic Interviewer for Cencio Solutions Corporation, servicing clients domestic and abroad.


In 2002, Mr. Nilsson started his own investigation company, and in 2007, he founded NTA Investigations and holds the position of CEO.


Mr. Nilsson is a leader in this ever-changing industry and continues to contribute his time and experience to its future. As he repeats in his training seminars: “The key to success is positive, pro-active communication and training.”
