34 years ago, Nancy and Ray took a gamble and launched their lifelong endeavor, Delta Investigations, later to become, Delta Group. Nancy earned a bachelor’s degree from Florida State University with a major in risk management and insurance. Prior to the Delta venture, she started her professional career as a commercial insurance underwriter and claims adjuster. This experience gave her an appreciative and well-informed perspective on the needs of adjusters in the fraud arena. Nancy is proud of Delta’s longstanding relationships with its partner clients and the results the company has relentlessly pursued over three decades. Nancy continues to oversee and administer the day to day operations of the company. Her proudest accomplishments, however, are her three children, Adam, Ross, and Sarah, their countless achievements, and the fine individuals they have become.
In company with Nancy, Raymond took a risk, withdrew their life savings and purchased his first camera to begin their surveillance career. 34 years later, Delta Group has attained a level of success Raymond could not have imagined the day he brought home that Sony Portapak. Raymond graduated with a bachelor’s degree in criminal justice from Florida State University before he began his career as an underwriter and claims adjuster at The Hartford, where he and Nancy met. Raymond pioneered Delta’s eRemote® camera and presented the industry with a product that would revolutionize the future of surveillance. He continues to be the driving force behind Delta’s dedication to staying on the forefront of technology through strategic innovation. He presents CEU credit courses and offers the private investigator eligibility class for the State of Georgia. Like Nancy, Raymond considers Delta’s success to be one of his greatest achievements; however, he believes life’s greatest accomplishment is seeing your children become successful, respectable individuals. He could not be prouder of his children’s accomplishments to date.
