“I recently attended a Tower Rescue Technician course held at the Mississippi State Fire Academy. The class was the first of its kind held on campus and was attended by some of the best rescuers the state has to offer. Cody spent the week with us, demonstrating techniques and answering any questions we had regarding the towers and technicians we may run across in a rescue situation. Cody’s knowledge of all aspects of the tower world was incredible. He had immediate answers for any question asked of him and showed many tips to make our time on the tower a lot more productive. He was able to make a contact to SBA and gain access to a live tower for us to do training on during the last day of the course. Everyone in the class truly appreciated having Cody around throughout the week. It would not have been the same without him. He represented Comtrain in a superior fashion. I hope I am able to conduct more training in the future with Cody or any of the staff at Comtrain.”
