“Really helpful staff. Also; good to support usps. Awesome mission serving all of USA.

Edit: yikes. Lots of Karen’s and Kevin’s in these reviews. Maybe don’t vote for people actively defunding the post office and they won’t be so stressed out to help y’all.”

“What great service. I needed a package mailed, and she took it upon herself to neatly create the shipping lablel and tape it well. I have had great service like this in other countries, but it is rare in the US. Great job.”

“I was weak and unable to stand up on my walker to wait for the VanGo bus to pick me and my homemaker back up for me to return home. My homemaker asked for a stool for me to sit down in the lobby, and the postal worker provided me one to sit on until the bus came.”

“It's a typical small town location. I often have to call out for an employee, but people are always available and nice. I even went here during the height of Covid when we had to form a line outside and go in one at a time. I've seen worst post offices”

“I have no complaints about my experience here. There were two people in front of me and two behind me and we all got the same treatment and respect. My own ignorance to what I needed to do was my only holdup but I was given accurate assistance to get what I needed done. They for sure sell stamps and can mail things certified.”

“I didn’t know this post office was here, pleasantly surprised. I first stopped at the one in my town of Troy and they had one employee working and a line of about 10 people and they all appeared to have 2+ boxes each in their arms. After waiting about 10 minutes, I had to leave for an appointment, but during that time only one person was helped. When I walked into this office both counters were open and there were two people ahead of me. The one window closed down after helping her customer, it was close to closing so to be expected. The other lady was very fast and efficient with her customers. She didn’t have much emotion as friendliness or any negativity, just professionalism, getting the job done and answering your questions and getting you in and out, I can respect that. The facility was clean. I read the reviews after I left and will leave the rating a 5 and will track my packages to ensure they arrive on time and without incident, if they do, I’ll keep the 5 and recommend this USPS Office.”
