Country music singer/songwriter Colton James recorded a music video at one of our manufacturing facilities to show his support for the 190 military veteran Associate-Owners that work throughout our company. His song, "Brave Men," is a tribute to all who served in the Armed Forces. Some of JASPER's military veteran Associates were asked to participate in James' video by contributing a picture of themselves in uniform for the video shoot.
"We are really excited to be at Jasper Engines & Transmissions, in the fact that you employ so many veterans across the country," said James. "One thing this video is going to stand for is going to be representing what all our brave men and women do."
