Supervisory Committee

As an independent body, one of the roles a Supervisory Committee performs for a credit union is to investigate members' complaints not resolved to their satisfaction by credit union management. So should you have any concerns or complaints, we ask that you attempt to resolve the issues with WyHy staff and management first. Should you feel your concerns or complaints have not been resolved to your satisfaction, you may submit your concerns or complaints to our Supervisory Committee in writing at the below address.
