Hello, I live at 219 W. Blithedale Ave., Mill Valley CA 94941 and Don is my regular carrier. I know he’s away on vacation but whomever is covering for him needs to know we have a very friendly dog. Please let them know. Thank you!


your stamp machine is broken. your online stamp ordering service will not let me create an account. how do i get stamps from you without coming in? i am part of the vulnerable population.


Today I overheard the difficulty an employee of here faced when visiting an Urgent Care center due to an on-the-job injury. The postmaster of this facility, Kim supposedly, refused to provide the employee or urgent care with information on who covers the employees when on-shift, and their policy number. The employee may pay out of pocket and get reimbursed, but not everyone can afford this. I could tell by the conversation the reception had with the postmaster that she was not friendly at all, and it seemed to upset the patient greatly. I can understand how nobody here answers phones, and has the general notion of not giving a shit, when that is how their postmaster treats them and apparently other professionals that she comes in contact with on a day to day basis. I am disgusted. -- what an understatement


I am disabled and use a mobility scooter to get around. I have a PO Box at your facility and I go there 3 to 4 times a week on average. Your counter staff people are always polite and helpful and I appreciate their service. However I have major problem with accessibility The front doors are heavy and difficult to open by a person in my condition. The Americans with isabilities Act requires that modifications. such as a door opening mechanism be installed in buildings open to the public. I, and other disabled patrons would appreciate your compliance as this situation has proven very troubling especially on rainy days. Thank you for your consideration.


I tried called to cancel an appointment to have Passport Photos taken tomorrow morning but no one answered the phone all week. The Mill Valley Staff are very cordial especially Monica. From EB : )


The phone hasn't been answered all day and now it's busy - my package has been "out for delivery" for two days. Now I know why USPS is going out of business!


Look up PAEA. It's because the Republicans require that the USPS prefund its future health care benefit payments to retirees for the next 75 years in a 10-year time span, meaning that it has to put aside billions of dollars to pay for the health benefits of employees it hasn't even hired yet, something that no other government or private Corporation is required to do. If it weren't for this the USPS would have a 1.5 billion dollar Surplus, but that's not what you Republicans won is it? No, you Republicans want to privatize everything.

I've tried to call the phone for days - no one ever picks up - just rings and rings and rings. I've had my mail forwarded temporarily - and it has yet to be delivered. The mix up is on the Mill Valley end, it seems. I'm finding USPS to be very unreliable and unprofessional in general! If they aren't going to pick up, then they shouldn't advertise the option of calling!


The guy in the Mill Valley Post Office who deals with passports is not helpful, pleasant, etc. Very unpleasant process.


I've tried for days to call to get a passport appointment and either it is busy or just rings and rings and nobody ever picks up. Very frustrating.


I have tried for 2 days to get through to someone on the phone. The line has been constantly busy - or no one answers the phone.


Please hang up your phone. I have an important message and your line is always busy!
