Welcome, Commerce State Bank Clients!

Commerce State Bank will become Summit Credit Union on October 1, 2022.1 It’s a decision both teams made together upon seeing what a great fit we are – from our service focus to our talented, helpful staff.

You’re going to LOVE what Summit has to offer.

Over the last year, Summit members saved an average of $291 per household.
And we can’t wait to see what we can do for you! Here’s a sneak peek:

More options

Free Checking and Student Free Checking, credit cards with rewards or cash back, more ways to build wealth, more mortgage options (still serviced locally), and more branch access.

More added value

Lower fees (more savings for you!), an annual cash give-back3 for saving and borrowing with us, and free financial education to meet any goal.

Continued security

Your funds stay insured up to $250,000 by the National Credit Union Administration, part of the Federal Government (just like the FDIC).


Key changes & other important info

Account changes will be minimal and at a benefit to you. There’s nothing you need to do right now, so just continue to:

  • Use your current Commerce State Bank checks, debit cards and any other products you have
  • Visit your current Commerce State Bank locations (they remain open and available to you)

Mid-September 2022

Current Commerce State Bank customers with business accounts will get an info packet with everything they need to know about changes as of October 1, 2022.

October 1, 2022

Commerce State Bank legally becomes Summit Credit Union, and you will notice these changes:

  • New signs – These will switch from Commerce State Bank to Summit Credit Union.
  • New social media – Posts to Commerce State Bank social media accounts will stop, but we’d love you to follow Summit Credit Union on Facebook, Instagram, Twitter, Snapchat and TikTok for events, specials and other updates.
