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.
