I have had an account with One Nevada (formerly Nevada Federal Credit Union) for almost 21 years now and have always had exemplary service. Have been with them through two auto loans (both professionally and rapidly handled) and an identity theft where both my checking and savings accounts were cleaned out (they restored all of the stolen funds in less than 48 hours).
The Lake Mead branch is not a full-service branch (no tellers); however, the staff on hand is always most accommodating and friendly. When I had a possible security breach on my debit card about a year ago, I went in and the card was replaced in less than ten minutes! (I was sure I'd have to wait 7-10 days to get a new card.) I am a very satisfied accountholder and plan to stay with this credit union for a long time to come.
