Best Expat bank to deal with (Denver)

Hi can anyone point me to the best bank to deal with being an expat? We currently bank with ING but I can only seem to find an Investor Centre, is that a normal everyday bank or is that a branch only dealing with large investments? I can't seem to get any clear answers. Is there a better bank to deal with being an expat? I'm aware that this is one of THE most important things to do upon arrival. Thanks for your help!
