- RMRichard MarvinMay 21, 20255.0Great small post office
- SCSusan ClarkDec 22, 20205.0I was so pleased with "Jim" at the PO today. I neglected to include a Space number for a Clayton address, and noticed it was held up in Clayton PO (after leaving Yosemite, then to Sac, to Oakland, then Clayton--all before Xmas!) I called Clayton PO, at an extremely busy time, and Jim answered, took the time to search, and located the package! The tracking info said it had been shipped back to my PO, which would've taken another week to get to our grandson! Thank you so much, Jim. You made another kid happier on Xmas!
- WNWoo In NorCalDec 31, 20185.0I have been using this Post Office for over 20 years now. It's a small PO that's overwhelmed sometimes because of their under staffing. But I have had nothing but good service from friendly PO workers there!
- DLDeborah LinnekinDec 15, 20165.0This is the best post office inn the area. They are very responsive to lines and wait on their customers quickly.
