This review is for their open business services on Saturday as this is when I usually visit for my mailing needs.
I cannot comment on their services for other business days, however, what I'm about to write has been consistently observed when I visit on Saturdays.
On Saturdays, the place is busy with very long lines that move at a glacial pace (-1). The staff I've encountered aren't bad in terms of customer service but they seem to work very slow (-1), and either there's only 1 or 2 clerks working behind the desk.
The inside is very small, so expect the entrances to be sometimes blocked by the long lines (-1).
The parking lot is also small, and with the long lines inside that barely move, don't expect to find an available spot anytime soon (-1).
If you have mailing needs, avoid this post office (at least on the weekend)!
