Merck Sharp & Dohme FCU (MSDFCU) is a full-service financial institution that has been serving its members since 1950. Like other financial institutions, we offer a full range of products and services. Federally insured by NCUA. Equal Housing Lender. Unlike for-profit banks, we are a not-for-profit Credit Union. Because we are not-for-profit, all earnings are returned to our members in the form of better rates on savings and loans, and additional products and services. Our Credit Union is staffed by professionals and governed by a volunteer board of directors, whom our members elect. MSDFCU is one of the largest credit unions in Pennsylvania.
