Our History

In September of 1955, Sam Petrosky, and his wife, Maxine, started Twin Specialties in a small bedroom in their apartment.  They utilized a small file cabinet, a typewriter, and a desk, to form a family business that has served manufacturing and industrial companies for decades.

Sam served as a combat medic in the U.S. army from 1943 to 1945. Upon returning from the war, Sam entered college at Drexel University, in Philadelphia.  However, he later transferred to PA Military College, now Widener University, and graduated in 1949.  At that time, PAMC offered a strong industrial engineering program, and that appealed to Sam.

Maxine, who kept the books for the business, graduated from Syracuse University.  In addition to the company’s bookkeeper, she also took care of her two children, Mike and Lynn.

Sam, unemployed after college, answered several ads in the newspaper.  He was soon hired by Henry E. Sanson & Sons.   After a few years there, Maxine’s father had suggested to Sam that he should explore the possibility of owning his own business, and Twin Specialties was founded.

Due to the couple’s hard work, it quickly grew.  Their first office space was located in the building at 111 Presidential Boulevard in Bala Cynwyd, PA.  Sam remembers that Twin was the second tenant in that building.  Another move came in 1989 to Conshohocken, PA, where the company currently conducts business.

In 1979, Sam’s son, Michael, joined the business.  Mike graduated from Syracuse University, and quickly formed a father and son team that worked very well together.  Sam’s daughter, Lynn, another Syracuse grad, assumed the role of office manager, in 1988.  With Sam’s knowledge of industrial products, and Mike’s energy and attention to detail, this family business has been serving their clients in the Delaware Valley for decades.

Since 1955, Twin Specialties, has relied on outstanding customer service, and personal relationships with its customers to become one of the preeminent suppliers of specialty lubricant, coolants, and rust preventatives in the area.
