About Us

The T.O.P Story

Train Out Pain Performance was co-founded in 2017 by Dr. Jason Ross and Eric Haslinger in Grand Rapids, Michigan with the launch of MOBI – a performance and recovery tool for athletes – which was successfully funded through Kickstarter. The spirit and roots of the product and company, however, began years earlier. 

“Our mission is to equip athletes with the tools and education to maintain a healthy body and stay on top of their game”

Dr. Ross started his early career as a college athlete and member of the US Bobsled Team. Since receiving his Doctor of Chiropractic degree from Palmer College, he has opened his own practice (Train Out Pain Chiropractic), served as the chiropractor of the US Bobsled Team at the 2010 Winter Olympics, and continues to train and treat athletes of all levels around the world. Throughout his career, Dr. Ross has experienced, seen, and treated the common issues that all athletes face: mobility, fatigue, and recovery. He teamed up with Eric and his Swytch Design team to develop a tool that empowered individuals to perform self-care on-the-go – and MOBI was born.
