Friends of the Restorium vice president Donna Jo Dirks presented facility maintenance supervisor Kevin Schnuerle a “Maintenance Superhero” photo today at a coffee reception in his honor at the Restorium on his final shift before retirement … though he’ll be at this Sunday’s annual Restorium BBQ from 11 a.m. to 1:30 p.m. as a volunteer, and he has officially volunteered as a groundskeeper.
