Six years ago we worked along side Johnson Industrial rehabilitating historic cabins.  Soon we began to understand they have the same philosophy in their trade as we have which has earned them our greatest respect.  After working alongside them for four years, I hired them to provide the plumbing for the Mariposa Grove South Entrance Station and an additional comfort station in Yosemite National Park. 

The quality of Johnson Industrial’s workmanship and overall concern for each project is unparalleled.  They are careful and methodical in their work, and it shows.  It is my pleasure to work with them.  I look forward to many more projects with them.
