History of Exodyne, Inc.

Founder Ralph Rockow formed Exodyne—a debt-free, privately-owned corporation dedicated to prioritizing the needs of its customers—according to three simple yet powerful principles:

  • Operate ethically
  • Meet all deadlines
  • Exceed customer expectations

It started in 1942 when Hugh DeHaven was appointed as a Cornell University Medical College research associate, which led to the formation of the Aviation Crash Injury Research group (AvCIR). Since then, a small pioneering research group has grown into a diversified and dynamic technical services company devoted to the same principles of science and safety that Hugh DeHaven embraced nearly a century ago.

Today, more than 37 years strong, Exodyne has one subsidiary: Dynamic Science, Inc. (DSI) as well as affiliate Exodyne Properties, Inc. (EPI).

Doug Rockow, President of Exodyne, manages the company on the same principles as Ralph.
