Vantage Credit Union | 1,675 followers on LinkedIn. Enhancing your life, strengthening our community. | Vantage Credit Union is a leading, full-service financial institution that’s owned and guided by our St. Louis-based member-owners—people just like you—and not by stockholders like at a publicly-traded bank. Because we’re a not-for-profit financial institution, our member-owners enjoy better rates, lower fees and superior service.
