- KRKiron RaoJan 31, 20265.0This is the tiniest post office I have ever been to and also the friendliest. Skip has a great sense of humor and will give you the best advice. This was not the closest post office relative to where I live but it was definitely worth the drive.
- DJDennis JohnsonDec 20, 20255.0They are always helpful when I am mailing packages to family for holidays and birthdays
- SSScott StillitanoNov 30, 20251.0On 10/19/2025 I mailed 3 money orders which added up to 2,300 dollars. These money orders were for first month's rent and security deposit. My new landlord said he received the payment on 11/30/2025. That is 42 days. Never trust the USPS with deliveries of any big payments. I was horrified, not knowing where that money was. It made me feel so powerless.
