Slide “I have had two occasions to engage the assistance of History Associates in ongoing legal cases, one in 1999 and a second one twenty years later in 2019. In both instances I have been impressed with the professionalism of the HAI historians in ferreting out needed documents from fifty to seventy years ago. HAI professionals are of high scholarly backgrounds. They do not over promise but have valuable insights of where lost documents may still be found. I do not hesitate in recommending them to any attorney who has a need for this kind of support.”

Slide “My research into the origins of Arizona’s modern securities act wasn’t coming up with anything, so I turned to History Associates for help. As historians, they knew the background of the industry and the key players involved right away. They got right to the bottom of the issue and identified potential sources for information, regularly updating me on their progress. They found material in the archives I never would have found, including correspondence from 1949 that showed the thinking processes behind the legislation. I would not have gotten there without their help.”
