Business Wire Transfer

Maximize the use of your funds - utilize wire transfers.


Wire transfers can be initiated three ways:

  • Electronically using our TM ConnectSM products

  • In person at a local banking center

Electronic wire transfers through our TM Connect products offer you the ability to:

  • Set up alerts for easy notification
  • Initiate wire transfers from your computer for convenience
  • Set up dual approval for additional security
  • Create templates for those wire transfers done on a repetitive basis
