The staff at First Security have always taken great care of me, I highly recommend this bank. Home town service and willingness to go over and above. I wish they had bill pay available as I travel a great deal and would be able to give them more of my business if that was and option.

When I needed a small loan for a vehicle purchase, I went to all three Deer Lodge banks and 1st Security was the easiest to work with, most willing to speak with me, and most receptive to my needs. I ended up using them for my loan. They continued to be personable, professional, and always helpful. I now have my loan paid off, but if I'm ever in need again, they will be my go-to!
