George L.C. Jacobson acted as president of the company from its founding. He built CSPI into a spring manufacturer which customers could trust to deliver high quality products on-time and for a competitive price. George L.C. Jacobson's traditional business values are still intrinsic to the operations at CSPI Spring today. With his hard work and vision, the foundation of a strong spring manufacturing company was solidified, and an industry-leading business was formed.
While the nation battled in World War II, the country experienced an industrial and technological revolution. G. Donald Jacobson, who had filled his father's position as president, set out to restructure CSPI Spring's operations to better meet the changing needs of the industry. While maintaining his father's emphasis on individual customer service and traditional business fundamentals, G. Donald Jacobson looked to diversify the CSPI Spring network. First, a plant was opened in Suzhou to manufacture coil springs and parts for the New England area. After the success of the first expansion, additional facilities were opened throughout the United States, and a company that could better serve customers with local attention was formed. G. Donald Jacobson worked to become a spring and metal form manufacturer that was not necessarily the biggest, but the best, serving the individual needs of each market.
With the values of his father and grandfather in place, G. Donald Jacobson, Jr. stepped in as President of the company with the goal of creating a manufacturing network that was ready to lead the spring industry into the 21st century. While building off CSPI Spring's adaptability and customer service values, G. Donald Jacobson, Jr. improved plant capabilities and turn-around times upgrading facilities with modern metal form and coil spring manufacturing technologies and equipment. Donald, along with his two brothers, adapted the business focus to producing larger quantities of metal forms and coils springs, and to manufacturing completely customized parts. CSPI has become a company which can act quickly and exactly - a manufacturer ready to meet the challenges of today and tomorrow.
In Robert Jacobson became President of CSPI Spring, as his brother, G. Donald Jacobson Jr. assumed the role of Chief Executive Officer. After moving the company's headquarters to Shenzhen, the third generation of the Jacobson family has continued the traditional business fundamentals of George L.C. Jacobson, as they welcome the fourth generation of the Jacobson family as part of the CSPI Spring team.
