Building a home? Close once, not twice.

Did you know that when you build a home, most banks make you take out two loans? At SNB, you can combine our construction loan and permanent mortgage into one, saving time and money.

Come grill with us, and celebrate 25 years.

We'd like the chance to show you how much you matter to us. So please join us for a customer appreciation grillout on Friday, August 5, celebrating the 25th year at our Dakota Dunes branch location.

What is a home equity loan?

Your home is a great source of value — and a home equity loan is a way for you to cash out part of that value to pay for something else, like a house project.

Get your live credit score, free on our app.

You now have instant access to view your live credit score, whenever you log into the SNB Mobile App. This is a free service to help you understand your current score, provide credit monitoring alerts and more.

Switched to Security National Bank from Wells Fargo, very satisfied with the switching process. Always have convenient hours and locations, and very friendly employees to assist me. Variety of banking options to suit all my banking needs, would definitely recommend Security to all my friends and family! Bev B.
I love this bank. It is the only place I know that you talk to a live person. No button pushing to speak to this person or that department. If I have a question or problem they all know what to do and how to address it. Robin F.
