Great staff! I had a great experience and even met the CEO. They made sure I knew about everything a credit has to offer. They even had snacks. Thank you to Shonna B. and Mady was nice too
I am leaving my review for the way, Miss Shonna treated me during my visit in the branch earlier this week. She showed the utmost professionalism while assisting me. I am grateful for the treatment shown to me from each branch that I visit.
