Have had the pleasure of dealing with Shari F. Lord on several different different occasions, even in bad situations, she has always made them end as a very positive experience. From the minute you enter her office, you will be in very capable, caring and professional hands. We not only look forward to future business with Del-One due to Shari F. Lord but also enjoy knowing we can recommend family & friends with the upmost confidence of high quality service!

I am definitely a proud member of the Del-One community and I appreciate all the great services they provide. They are very helpful in the sense I left my ID in a hurry to get to class and thanks to the women who turned in my ID and the help of my newly released favorite clerk Tizarra, i got my ID back with a smile. Thank you so much and i am greatly appreciative.

I love this bank! I've been with them for over 15 years and they give the best service. Lisa Brewer is amazing! She has helped me out so many times and made everything so easy. Her great service is one of my favorite things about this bank. The ladies at the downtown Dover branch are great as well!
