Tammy, the Post Master, and her crew are great! They are always courteous and efficient and we always get our mail delivered on time and without error. They have also been very accommodating with special requests. I can't imagine how hard they work to make this happen 6 days/week. I want to thank them for all they do.


So, I made a passport appointment on Friday 2/16, online. I received a confirmation on Sat 2/17 and I received an email reminder on Thursday 2/22. This morning (2/23) my husband brought his kids there. He was told that passports were only done by appointment and they had no appointments for the day. When he showed the woman the confirmation email she said “Oh yeah, you must have made it after 8am today”. She then begrudgingly took their info. If you come here make sure you have all your ducks in a row!
