Dennis spends a great deal of time working with tort litigation issues revolving around chemical applications. He will be the first to tell you that professionalism and strong education programs will help you provide a better service and may be a real asset should you be unlucky enough to find yourself defending your application to regulatory bodies or the courts.

Dennis recently started an aviation insurance agency and is very active with that in the agricultural aviation community. Dennis plans to continue working with agricultural aviation as a consultant conducting educational programs, fly-ins, field research, litigation work, aviation insurance, and perhaps a bit more time to do ag flying.
