Steve Cummins

Board Treasurer


I’m a lifelong Mansfield resident and have been with the company since 1987, serving a variety of roles in Operations, Quality and Engineering. I’ve enjoyed watching our company grow and have fond memories as a child of coming to work with my father on Saturdays. I’ve been around just long enough to be amazed and amused by the passing trends and fads that come in and out of the business world. From my grandfather on down through my father, and brother and I – we’ve found that by truly listening to our customers, sticking to basics and treating people the way that we would like to be treated, a business can flourish and grow. Who’d a thunk! I am a graduate of Kenyon College and live in rural Mansfield with my children, and a menagerie of animals. Oh, and I have a wife too.
