15 Stars for Waste Training!
“We had five total safety classes with Cornerstone and wanted to say people are very happy with the classes. They are engaged and continue to ask questions. I have had multiple people ask me if they could give the classes fifteen stars. The instructor was very knowledgeable, and our team is excited to have Cornerstone back next year.”
