In Loving Memory of Doug Andersen
Periogen co-founder James D. (Doug) Andersen passed away Monday, July 8, 2019 after a long illness. A brilliant inventor, engineer, and visionary, Doug’s patents and technology span a broad segment of our culture including aviation where his safety technology is in every Boeing aircraft made. Of all his efforts he was most proud of the development of Periogen Oral Rinse that has so positively impacted the lives of people the world over. Doug will be missed.
