About Us

Terry Gwinnup, President
Terry is a true American success story.  Growing up in the small Indiana town of Milroy, Terry went to work in the local paper mill.  But the dream of being his own boss drove him to work nights for a paycheck and start a business during the day.  The first venture was lawn care.  Taking a bit of a risk, and against the advice of some around him, he bought a mower that could handle the volume of work.  Hard work opened the door to quit the night job and go full time chasing a dream.  Lawn care led to environmental restoration, and that's when things took off. 10 long years of growing Gwinnup's Restoration allowed him to not only take care of his family, but to expand into other areas. As an owner of three businesses in Rush County and with the goal of giving back to the community, Terry Gwinnup is an American success story. STS is very proud of our CEO and all of us are honored to join him in chasing this dream of making the best bike we can.
