there are many banks in Coronado, check out the link

Banco Nacional is the Panamanian bank, nice people but no one speaks English, and no internet access.
I deal with Global, they speak some English, I have had a good relationship. They are in the Rey shopping complex.
Multibank is new in town, they have been promoting well their products, the Mgr speaks English and it is in the Village complex (on the highway). Mario A Quezada Garcia-Maritano, General Mgr, tel: 507 240-205 e:

They gave CASA (Coronado Area Social Association) 60 fabric bags for the Xmas basket last December.
Hope this helps!
