Witmer Motor Service began in 1964 in the two-car garage of Arnold Witmer. This one-man shop served the rural community of Martindale, Pennsylvania. The need for electric motor repair was one of the demands which Mr. Witmer was prepared to meet.

As the demand for electric motor sales and repair grew, Arnold Witmer's two sons, Marvin and David, entered the business. The two-car garage quickly became too small to house the growing business and in 1986, the business was moved to a new facility built in Reamstown, PA.

In 2007, Witmer Motor Service expanded by acquiring 322 Electric Motor & Tool in Hinkletown, PA. With this acquisition, Witmer Motor Service expanded to include Power Tool Sales and Service.

In 2012, Witmer Motor Service launched witmermotorservice.com, bringing their expertise, products and services to a much larger community.

Witmer Motor Service continues to be a family owned and operated business. The Witmer family is grateful to God for the heritage of diligence, initiative and Christian faith which enabled Arnold Witmer to establish this business. This heritage continues today as WMS continues to provide Electric Motor and Power Tool Sales and Service to their community.
