Would have made this my new bank if they didn't give me hassle for paying my property tax.

A great, big thank you to Maria Luisa Mesina for helping my family with services provided. She is a very compassionate, intelligent and helpful individual. She went above and beyond when assisting my family and I prior to closing. Next time I am in need of assistance, I will absolutely be coming back to this bank and asking for her!
