Sound Federal Credit Union (SFCU) was established in 1952 to provide financial services to the City of Stamford employees and their families. In 2013, we opened up our membership to anyone who lives, works, attends school, worships or volunteers in southern Fairfield County. Since we first opened our doors, SFCU has been committed to providing our members with personal service, value and convenience. We know you are not just a number, but an individual with specific financial needs. Whether you have $25 or $100,000 at SFCU, you can expect the same quality service.
