“I have had the pleasure of working with Rick and his team at Entek for about 20 years now. They are always quick to respond to our requests and assist with the best solution to keep our staff safe. They have provided numerous trainings for asbestos, lead and mold to our Building Maintenance and Capital Improvements staff. They have also provided testing, reports and specifications for the demolition or our old buildings, and other suspect materials over the years. Rick and his team are all very knowledgeable, which is helpful in situations where staff are concerned about their safety. I highly recommend Entek for any of your environmental needs.”
