TSI is a Manufacturers Representative firm with a long history of serving the electronic industry in the Mid-Atlantic States. Our beginning coincides with the very dawn of radio, but our founder's interest in electronics began before that. As a teenager Wilmer Trinkle was building components by hand and working his wireless equipment in Philadelphia. After his military service in World War I Wilmer worked as an engineer for the Bell Telephone Company. At the same time, he was the Technical Editor for the Public Ledger now known as the Philadelphia Inquirer.
One of Wilmer's regular readers was the owner of a manufacturers' representative firm named L.P. Clark, whose firm Trinkle joined in 1924. Clark died in 1931 and Wilmer bought the firm from Clark's widow. This places TSI as one of the first firms formed that is still in existence in the USA and the first resulting from an acquisition to continue.
Wilmer's son Bob stepped in after his fathers sudden death in the mid 50's and guided the firm until Dec 1999 when Bob Albert and Pete Thomas assumed ownership.
Today, we are owned by Russ Skog of Brandon Associates (BAI). We are now part of a dynamic combined organization committed to bringing suplier excellence through our collaborative efforts.
