TIMELINE
1909  
  Roots of The Westerman Companies are planted in Bremen, Ohio by Claude C. Westerman and Charles Heck, founders of the oldest continuous manufacturer of oil and natural gas wellhead equipment in the Appalachian area.

1911  
  Claude Westerman brings his brother Guy into the business as a partner after buying out Charles Heck's half interest. The enterprise—Westerman Brothers Boiler and Tank Works—thrives as Bremen finds itself in the heart of an oil and natural gas boom. Oil derricks and pumps dot the Southern Ohio countryside. The Westermans are innovators—originators of the first rotary cleaning tools for boiler tubes and pipe, the all-steel toolbox, derrick forge and slack tub, and the now-famous Westerman automatic oil and gas separator, which is manufactured and sold today in essentially the same form as Claude Westerman's original design.

1918  
  The Westerman brothers start a draying business in New Straitsville, Ohio, an offshoot of their dependence on horses and wagons, which they drive into the field to repair boilers.

1957  
  Claude Westerman sells the company to its present owners and the name is changed to Westerman, Inc. The ensuing quarter-century sees Westerman gain enormous success in the manufacture, sale and delivery of oil storage tanks, oil and gas separators, wellhead equipment, and large and small pressure vessels. The firm becomes one of the original companies to qualify for National Board of Boiler and Pressure Vessel Inspection approval.

1979  
  Westerman broadens its product line and customer base by becoming the national distributor for widely respected Alten oilfield pumping units manufactured by Alten Foundry and Machine Co. in Lancaster, Ohio.

1983  
  Westerman buys Alten, which had fallen on hard times, to preserve that company's outstanding gear reducer product line. The Alten acquisition gives Westerman access to many new markets. Among them: marine hoists for the dry-docking of ships in both military and commercial applications.

1984  
  The company moves into the world of electronics by establishing the Westerman Controls Division, producer of supervisory control and data acquisition (SCADA) systems and related hardware and software.

1986  
  Westerman enters the nuclear energy market using an UF6 cylinder design and manufacturing expertise for its first contract with the United States Department of Energy. The same year, the company acquires the technological and engineering expertise of a Toledo manufacturer of fiberglass reinforced plastics, establishes the Interstate Plastics Division in a 30.000 sq. ft. plant in Lancaster, and moves its administrative operations to this facility.

1989  
  Taking a bold step back to its roots…and back to its future…Westerman purchases a significant piece of real estate, previously owned by a longtime competitor, on Broad Street in Bremen—a 75,000 sq. ft. office-warehouse-manufacturing facility in the same block with the plant that houses its steel fabrication operations.

2000  
  Westerman acquires Wooster Tool & Supply Company, the premier producer of oil field pressure vessels. The same year, Westerman sharpens its focus and completes the return to its long-standing product and knowledge base by closing and selling the equipment of the Interstate Plastics Division.

Today Westerman is experiencing healthy, organic growth: steadily expanding its operations, its sales and profits by responding to customer needs with innovative solutions, superior products, and a commitment to uncommon service that has been nurtured for nearly a century.

2006  
  Westerman Rocky Mountain, a wholly owned subsidiary, is established in Evans, Colorado. Its mission: to sell and service oil and gas products, primarily oil and gas separators and production units, throughout a wide Western U.S. market area.

This newest addition to the corporate family is further evidence that Westerman is experiencing healthy, organic growth: steadily expanding its operations, its sales and profits by responding to customer needs with innovative solutions, superior products, and a commitment to uncommon service that has been nurtured for nearly a century.
