What does it take to be a member? Membership is open to those who live or work in Aurora, Montgomery, or Kendall County, along with several Employer Select Groups (SEG's), such as the Burlington Northern Santa-Fe Railway and the Dial Corporation (and their affiliates). When you join, your initial deposit into your savings account is what makes you a member! After that, all credit union services are open to you. FVCU also has family membership. Since you are a member, your family members can also join. Contact us at 630-859-2393 or send an inquiry to info@foxvalleycu.com for more information.
