    Well I guess it's my fault for not reading the reviews before driving to this post office. Lobby locked and the useless dropbox outside only takes skinny letters. I have a parcel that is 6x7" and less than an inch thick so I guess I need to take time off work to mail it????

    Why is the lobby locked and not open for access to P.O. Boxes after hours? I chose this post office for a P.O. Box because it’s on my way home from work instead of driving 20 minutes past my home to the Frederick location. I work 8-5:30 mon-Friday and 8-1 on Saturdays. I literally cannot get to my mail, ever. There’s a door that locks away the counter area so that’s secure, so why can’t we get to our mail? In addition to this, I ordered and paid for the box online and when I went to pick up my keys I was told I still had to fill out a paper copy “for his records”… why? You have all my information in your system, that’s your record.

    Even though this location is small, it has a wonderful staff. They're very friendly and family oriented. I always enjoy going to this PO as it feels like I'm seeing close friends or family. They always help me with anything I need. Often times, when going to larger locations, you get the quick, hurry and rush out the door attitude. Not here. I love this place.

    This post office could use a upgrade. It's a old 1400sq ft 1960s house converted into a postal office. With the increase in population in the area, this post office should be rebuilt to today's standards. There should be automatic doors for ppl carrying in/out large packages, and for the elderly or disabled. The lobby/check out area is super tiny, only a 3 or 4 ppl can stand in there at a time. There should be a automated self service mailing kiosk to prevent long lines. But in this office, it's so tiny, no kiosk can fit inside. I have received my neighbor's mail, but for the most part, I do get my mail consistently. I hate when the postal delivery person marks packages as delivered, but instead they deliver it the next day or a couple days later! Need new facility, but keep the staff....they are super friendly and helpful!

    The displays allowed me to pick my envelope quickly. The writing surfaces allowed me to address the envelop and insert the material I was sending. AND the person that helped my was friendly, knowledgeable, and talkative. The entire experience was pleasant.
