    Getting anything done with this bank is miserable and I dread every time I have to hold 20 min for a simple question. They also dont update balances on the weekend accurately and the card declines when you are trying to pay a bill, as the app doesnt show the balance. I have been a WSB customer and since the merger features and services have been removed or gone backwards. This review is O2 as a whole not anynone branch

    Mercedes Delcid has defined customer service. Always goes the extra to help you with your banking needs. I highly recommend her and her team when you have a need or banking service.

    I recently opened a checking account at this bank and had a smooth experience. The staff was very helpful and attentive, especially Krystal, who guided me through the process with patience and professionalism. Everything was explained clearly, and the account setup was quick and easy. I highly recommend this branch for anyone looking to open an account.

    Came in to cash a check, from a trust. Rudy started the process, Krystal did all the paperwork for me, and helped me get all the information I would need. Excellent service! Thanks
