Introducing the New SNB Debit Card

We're adapting to the way people bank today — including how you use your debit card. The new vertical design brings chip technology to the forefront, for a more intuitive and secure way to make a purchase.

Your Phone’s a Bank, Too. 

Whether you’re checking your balance, transferring funds, paying a friend or depositing a check with your smartphone — convenience matters to you and it matters to us, too.

If It Matters to You, It Matters to Us.

We have a new logo and a new look at Security National Bank, but we have not changed our commitment to serving you.

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.
