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!

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.
