- RRRFeb 3, 20265.0I’ve been using this post office quite often and I appreciate how professional and kind everyone is at this location. I came for a passport service and it was very smooth, Matt and Harpreet helped me and made sure I was all set to send the application to DS. The USPS website for rescheduling appointments doesn’t work, be wary of that.
- SBSteve BierJan 27, 20253.0I've never had an issue, per se....but for the love of all things big and small...ANSWER YOUR PHONES! I tried calling them regarding a package; no answer. Figuring that they were busy, I drove down there to claim it. There was only ONE OTHER person in the lobby. The main phone was ringing, and an employee looked at it, and ignored it. Way to go...
- ARAnn RNov 4, 20235.0First time to ship via USPS to send my sister some medical supplies that she will need for her treatment, Maureen was so nice and helped me from start to end. Maureen, you are awesome, you’re very accomodating and patient with me. Thank you!
