“This branch has by far the best service in terms of ensuring customer satisfaction as well as educating customers on the types of accounts you can open. The staff are extremely friendly, hard working, and knowledgable. If you want to choose a bank with great service and great staff, I would strongly suggest choosing RBB Diamond Bar.”
“I’ve been banking here for decades, and every time I’ve thought about switching banks, I always end up staying because of this team. They greet me with respect every time I walk through the door, and any time an issue comes up, they find a way to resolve it quickly and professionally.
Kelly, Ella, and the rest of the staff consistently go the extra mile to make my day. Their service, patience, and genuine kindness are truly rare. I’m more than happy with this branch, this team is an absolute gem.
Highly recommend banking here.”
“I had an excellent experience working with the Private Client Banker Amanjit Bains and advisor Josie Chuang at Chase Bank. They were incredibly competent, professional, and efficient in helping me resolve my issues. What really stood out was how much they valued my time—everything was handled smoothly without unnecessary delays or back-and-forth.
They were able to solve a problem that another branch had me running around for almost a month, which I truly appreciated. On top of that, they provided very detailed explanations of investment options and associated risks, making sure I fully understood everything before making any decisions.
Compared to the Chase branch next to Walmart on Grand, the difference was night and day. This team was organized, responsive, and truly client-focused. I felt heard, respected, and genuinely taken care of throughout the entire process.”
“Uyen (Gwen) was very helpful with walking me through a few transactions that I was unfamiliar with. Understanding and patient. Overall, made my banking experience a breeze!”
“I don’t have an account with them, but every time I used their ATM to withdraw cash, it was in service and operated smoothly. I also appreciated not having to wait in long lines. Overall, my experience with their ATM services was excellent.”
“Their manager is a super nice lady. She is very patient and always explains things clearly to her colleagues. I think the people who work in this branch are very lucky! Their bank is not busy at all so you don't have to wait. staff is very friendly.”
“This bank is being much better run than my previous visit. I’m impressed. They even gave me 9 temporary checks free of charge on my my order. ??????????!!”
“Janice Xin was very patient, responsive, and professional when helping my husband and me. She went above and beyond to assist us, and we truly appreciate her excellent service and extra effort.”
“Hello everyone,
I have been visiting this location for many years, and the reason I always come back is because of Rick, the manager. He is extremely professional, always welcoming, and brings great energy to this branch. The entire team here reflects his leadership.
In my opinion, Rick deserves to be working at the main corporate office of U.S. Bank. Although he is the manager of this branch, his skills and professionalism are at a level far beyond that. He treats customers and employees with respect, and he always knows exactly what is happening in his branch.
As a business owner myself, I wish I had managers like Rick. God bless him, and thank you.”
“This is the first time I found out that this bank exists in Walnut. It's a very small bank located at the very end corner of a Korean business center at Brea Canyon Rd. The employees, all ladies, are very nice and friendly, greeting everyone who steps inside the bank (in Korean), and not forgetting to say "thank you" when their customers are leaving. We came here twice to open new accounts. Mrs. Kim was very helpful and detailed, though she did not talk much in English. Still, she, together with others, make us feel welcomed. It's a nice local bank, convenient with a Korean supermarket next door for some grocery shopping. It doesn't have many offers for investments, but its employees sure give their utmost care and service.”

Everyone was professional and patient.
Merry Christmas! ?”
“Extremely impressed with the CTBC Bank team in Diamond Bar! I worked mostly with Financial Relationship Officer Mahina Zang to set up an attorney client trust account, and she was always accessible by phone and email. First Vice President James Lin and Vice President Timothy Lin were also fantastic to work with. They treat you like a valued client from the moment you walk in. Outstanding service all around!”
