John Diener

John DienerInstallation Foreman


As an installation foreman for Rodem John can be found rolling up his sleeves to get down to work at a number of plants anywhere in Rodem’s territory and beyond on any given day. Rodem is in John’s blood, being the oldest grandson (and namesake… his real name is Robert John!) of founder Bob Diener, he is one of eight third generation family members that work here. With Rodem since 2006, John has worked in shipping and receiving, procurement, and installation, but has found his niche running small crews for field work.


Although John travels throughout the country to visit various customers, he calls Southeastern Indiana home where he enjoys any type of outdoor recreation, hunting, fishing and spending time with family and friends.
