Every time I’ve stopped at this post office the customer service has been outstanding and the workers are thorough, attentive and helpful. Some days are busy and you need a lot of patience when there only two people behind the counter, but every interaction I’ve had has been wonderful.

Jose and everyone at this post office were amazing. I came in today to mail my wedding invitations, and he was incredibly knowledgeable, kind, and patient throughout the process. He is also bilingual! Really appreciated the help and positive experience.
