I had a great experience here at this location in regards to their Passport services. Passport services are by APPOINTMENT ONLY. It was super easy to book an in person appointment online through the USPS website. When I arrived, it was busy as usual & there was a line. They separated the lines into two, with passports standing to the side. Per appointments, it went by pretty quick. Christy provided amazing guest service. She was efficient, thorough, friendly and quick. It was my first time applying for a passport and she guided me step by step with ease. They do provide money orders & on site passport photos. I was in and out the post office within 20 minutes. Limited parking in the front. Handicap accessible. Self service kiosk desk available.

This is the worse post office I have ever encountered. We constantly received mails for other companies. The delivery person simply can not read the address and unable to deliver mails to the correct address. Moreover, we have not receive any mails for over 2 weeks because someone tried to break in to the mail boxes at the address. The post office simply stopped deliver mails to the box without telling all the tenants that we will have to pick up the mails at the post office. Extremely poor service!!!

They rarely answer the phone. Why have a number if you don't bother picking up the phone???
