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.
Received a call yesterday from the Security National Bank Fraud Dept. They had detected a suspicious internet purchase a couple weeks ago to Victoria Secret, that we had not done. Thank you so much for watching our accounts. Reginald M.
Recently moved back and switched to Security because our old bank was closing. Everything was very quick and easy upon signing up. I really like the people and they have lots of locations around town. They have an app which is nice and easy to navigate. I would definitely recommend Security. Shelby C.
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.
