“I wanted to email you and say thank you for all your company has done to help us with our Trenton Facility. Dave, Troy and Steve have mentioned on many occasions how grateful they are for having Blackburn on site. Please tell all your people that were involved at Trenton thanks for their efforts and dedication to our company and working through the project challenges.  

A special thanks for helping us through this difficult situation last week. I know that it was a little crazy at times, but because of your dedicated people we kept the facility running and serving our customers.

Thanks again for all you do to help us on these facilities.”
