Wow, Doug in the Fort Post office was so incredibly helpful when I shipped a very expensive item by Registered mail, He deserves a medal. Thanks Doug!


We are wondering why we used to get our mail around 1 in the afternoon and now we are getting it later and later. Today is October 26th and it is 6:10 pm and we still have not gotten it tonight. Getting very frustrated


Thank you to the Fort Atkinson Post Office. I recently had to send my son some hand sanitizer, disinfectant wipes and liquid soap to NYC where he could not find any to purchase. I took the package in unsealed to see if it would be okay to mail. The postal worker was very helpful and said that due to the flammability of the hand sanitizer it would need to be ground shipped. My son received the package on the suggested date and has since arrived home safely. I am very grateful for all that the post office does for us on a daily basis and hope that this essential service will never be underfunded by our federal government. Thanks for all you do!


I agree with Beth! I enjoy my visits to the Fort Post Office. Everybody is patient and helpful, even in times when the line stretches out the door! And to me it's amazing that the US Mail gets where it's supposed to go and in a timely manner, with such a reasonable cost! Well done! And Jim is a uber-friendly neighborhood mail carrier!!


The US Post Office in Fort Atkinson is a great place. The counter people are knowledgeable, friendly, and helpful. The building is cool. I like the post office and appreciate all of the work it does.
