- SESusan ErhartFeb 23, 20265.0Super friendly fast service at this location! Veronica is awesome 👌
- AEAmanda EspinozaFeb 17, 20261.0Put a piece of mail out in the mailbox to be picked up by the mail lady that was done last Monday (2/9/2026) and today (2/17/2026) my mail that I put out last Monday is still setting in the box. All while the mail lady has came by and delivered mail since then...she fails to pick up the outgoing mail. And I will add, she doesn't even come deliver mail consistently but has came by a couple times since last Monday. Still fails to actually complete her job though. Horrible employees at this post office, over the years (the last 16 years I've lived here) it has for sure gone done hill.
- NDNR DistFeb 8, 20261.0The mailman that delivered to summit estates off of Hoff road is useless. Worst mailman ever and doesn’t even pick up mail. He will leave it in the mailbox and refused to do his job.
- SASharhabel awawdaFeb 2, 20261.0Veryyyyyyyy veryyyyyy bad services I have a small business they don’t pickup I call so many times they don’t pick up at all why do you have a pickup service then or phones I understand it’s busy but at least answer the phone
- JWJeremy WellsJan 26, 20261.0I mailed in two pair of Maui Jim sunglasses for repair. I received a call from Maui Jim 11 days after the package was supposed to arrive that they received an empty box. Someone from USPS must have opened the box and stole them. Never using this post office again!
