Accounts for Minors

Open accounts for people under 18 years of age either with a parent/guardian or as a Uniform Transfer to Minors Account (UTMA). If parents are opening a joint account, use our standard account application; if not, use our custodial account application. Since minors do not have the legal capacity to contract, we cannot normally provide access devices to minors.

You Become a Member-Owner

We don't exist to enhance the wealth of our shareholders, we are member-owned. As a not-for-profit organization, we use our profits to increase Member benefits and support community causes.


Your Money is Insured & Protected

Instead of being covered under FDIC, your deposits are covered under the National Credit Union Administration (NCUA), which insures deposits up to $250,000, the same amount as the FDIC. It’s a different name but the same function.
