- MTMichael Turner6 days ago5.0Quick, and both people behind the counter were polite, helpful, and professional.
- EMElizabeth MillerAug 4, 20265.0Every 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.
- KLKriscia LópezJul 2, 20261.0The person in charge provides poor service; they are not friendly, and you don't feel comfortable asking questions because they don't handle inquiries well.
- MAMari AMay 6, 20265.0Jose 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.
