Secrets to Entrepreneurial Success with NH1 News

The Nason Group's mission is to help our clients in their time of need. We know that hiring a private investigator or process server can be tough. Our goal is to make it as easy on you as possible. When life gets hard, ask The Nason Group for help. 

The Nason Group, originally known as Nason Investigations, was founded in 2005 by Seldon (Don) Nason, Jr. Over the past decade, The Nason Group has been built into a very successful and professional investigation and litigation support company.  In 2010, Don’s daughter, Kristin Nason became a licensed investigator and joined the team. In 2017, Kristin became the sole owner of The Nason Group as Don Nason began his new career. Together, the pair have continued to build The Nason Group with a network of associates and team members providing a wide range of investigation and process service needs.

Over the past 18 years, The Nason Group has had a wide range of experiences with investigations. As well as working nationwide, from New Hampshire to California, The Nason Group has worked cases in Puerto Rico, Canada, England, France, Italy and Poland. With over 30 years of experience in law enforcement and international investigations, The Nason Group has many contacts with authorities throughout the world. 

It would be difficult to handle our caseload and provide expert service without the assistance of our other licensed associates. The Nason Group has several private investigators licensed through its agency and networks both nationwide and internationally.
