I walked up to the boxes to find my mortgage mail on the ground. Everyday their is someone's mail in another person's box. These are the simple mistakes that can have lasting consequences. Please be more aware of what you are doing.


I have made a several complaints and comments in regards to the delivery service......our post postal worker multiple times has stuffed over size packages, crammed, left on top of our mail box, thrown out of the vehicle into the yard and now just chooses not to deliver our postal.


I just wanted to recognize the Dorr Post Office. I had a very helpful associate who helped me with a certified mail tracking. I was very appreciative to get a live person AND such a helpful, friendly person to help me.
