I will NEVER use Brentwood USPS to ship items. During the year I ship small packages and unless I ship them priority, this post office will hold them for days on end until they feel like shipping them out. Last week, 5/30/17, I dropped of six packages before the post office opened, in the inside drop box, at around 8:30 am. These packages were not scanned into the system until after 11 pm the same day. Today, 6/5/17, I asked my mom to bring a package to be scanned to be sure it was scanned before 11 am. The woman at the desk told her (my mother) that they have a FEE they charge if they have to scan a package while the customer is standing there. When I called another local post office, they had never heard of such a thing. The current employees either need to be re-trained or retired for more efficient staff!

We had a hold on our mail from 3-4-17 until 3-15-17- The mail was stuffed in the mail box with some small packages and couldn't even close the top part of our mail box as mail was to full. Some of the larger packages were on our front door. I know our regular mailman would never do this. I had to make two trips to our box in order to empty it. Our regular mailman would never do this, When weve had mail held before he would bring it to us in a crate and ring the doorbell. I am very dissapointed in how this was handled. Margot

Weekend staff is nice. However, morning staff is the worst in weekdays. They are unfriendly,lazy, and rude. Window staff doesn't want to help pick up for vacation hold, you need to keep knocking the pick up door hard because the ring is broken. Really sad that I need to go this location to pick up because of my zip code. Hope they can be little nicer and work better.

Be careful. This location does not respond to electronic request for vacation hold or temporary forwarding.
