Our History

The Ohio Willow Wood Company, Inc. was founded in 1907 by William E. Arbogast, a bilateral amputee, on his family farm in Pickaway County. What started as one man carving and curing willow wood for prosthetic use has evolved into an international company which remains located in rural Mt. Sterling, Ohio. The company has a close network of 20 distributors worldwide. Today, the third and fourth generations of Arbogasts are leading the company in its expanded product markets and continued product innovation.

The Arbogast family and Ohio Willow Wood have been active forces in the O&P industry since its inception. The company was founded with the mission to provide quality prosthetic products that allow amputees to lead functionally normal lifestyles and to be comfortable when wearing their prostheses.

The Arbogast family has dealt with several business challenges over the past 100 years and survived thanks to some unique solutions. During the Great Depression Ohio Willow Wood diversified its product line beyond prosthetic products, manufacturing and selling wooden polo mallets and balls. The diversification succeeded in allowing the company to survive. In the midst of the depression, a factory fire destroyed the entire plant. However the Arbogast family and employees rebuilt the company in one month and retained their customer base. During World War II, Ohio Willow Wood augmented its manufacturing with government defense contracts to make parts for the Navy’s PT Boats and the Army’s B-17 Bombers.

During its 100-year history, Ohio Willow Wood has remained steadfast in its mission and has been committed to a spirit of innovation in its product design and development. Accomplishments in the industry have included:
