On June 20, 1950, employees of Latrobe Electric Steel Company, now Carpenter Technology Corporation, obtained a federal charter from the National Credit Union Administration and began Lesco Federal Credit Union. The first "office" was in the treasurer's home, followed by a small garage office near the steel plant. On April 4th, 1960, Lesco Federal Credit Union moved to 6 Avenue D, where it remained for the next 55 years, until moving to its present location on August 17, 2015. In 2005, Lesco became a community credit union, opening its membership to Westmoreland County. Anyone who lives, works, worships, attends school or volunteers in Westmoreland County is eligible to join the credit union. As a credit union, Lesco is a member-owned, full service financial institution. When you become a member, you are an owner of the credit union.
