We selected On Site Companies for the University Of Minnesota Biomedical Discovery District project for their price and service. I would recommend them for any project their service and attention to detail has been top notch. They have responded to all our needs and have been a great partner for this project. Thanks.
“Thank you for doing your ‘usual’ great job at the Caponi Art Park Bluegrass Festival. Your install team were VERY accommodating to and represented our park in the best possible light. We highly recommend your service and look forward to working with you in the future!”
“Yogi” Rueff, Owner Caponi Art Park
“I can say I’ve never appreciated a portable restroom as much as I did this weekend. Not only the availability of the units at each of our stops when we exchanged runners, but also the awesome service provided by a local restroom operator.”
