- ASAllyson SellersDec 5, 20255.0This post office, and staff, ROCK! I’ve had crazy things happen and Jolene is a hero. She is a mover and a shaker who gets things done. Keep up the great work; we appreciate you.
- DMDaniel MarquezNov 25, 20255.0The staff here at Gilroy post office are always always so very nice and friendly. Never had a bad experience with them. Sometimes it’s out of their control with some issues and the people get mad at them when it isn’t their fault. I will always recommend the Gilroy PO they are the best. Went to get my passport this morning was very fast and helpful
