- SSsaz999Apr 8, 20255.0I have never been in a more caring, friendly, knowledgeable and professional post office as the upper lake post office in upper lake California.
- CAC A.May 23, 20221.0The guy at the counter is so rude! Geez it really seems he hates his job but it isn't our fault. I wish they would find nicer people to work here because I love this little town.
- AMAshley MoranDec 4, 20181.0The mail used to come around 2 PM, but now it doesn't come until 6 PM and if you try getting a hold of the post office the wait time to talk to someone is an hour. Seriously frustrating!
