Ricardo N., Los Alamos, NM Says:

Top-notch bank.

Would highly recommend. And they're actually friendly as well!

Sylvie P., Santa Fe, NM Says:

The staff at the Eldorado Branch of the First National 1870 are truly exceptional.

If short wait times and friendly, courteous service are important to you, this should be your bank. At a time when “service” is virtually non-existent, the Eldorado Branch performs very well.

Tiffany P., Los Alamos, NM Says:

Great customer service.

And fast follow up when I had questions.
