Quest Diagnostics 447 Miller Avenue, Mill Valley, CA 94941

"Nothing good about this lab! Go elsewhere if possible ? You will be seen late even if you have an appointment , as the people are somewhat surly that work there, because they are chronically short staffed... Quest gets very low marks for any sort of customer service."

"Quest is the worst lab I have ever had to use. THE WORST EVER!! If you can choose another lab, do so! Even with an appointment there is always a wait because they do not hire enough staff. We have a growing and aging population in Mill Valley and they fire staff. I hate them. Their website has non-existent patient communication. They should not be allowed to do business in California. Welcome to 21st century health care. No patient care. Only concerned with bottom line. I live 2 blocks from Quest in Mill Valley but will drive to Novato to try Labcorp, hoping they are better."

"I was the first person in the office and the first person on the standby list. Two hours in I was told that it could be a few more hours before I was seen. I will go somewhere else."

"4 hour wait for walk ins at 11am and still was number 6 on waiting list (started at number 2 4 hours earlier). Joined one medical for a faster blood draw."

"Even a simple time sensitive drop off of prepared specimens is a big ordeal here. For something that one can’t even make an appointment for the wait is unacceptable. Additionally, my first attempt I tried 25 minutes before they were supposed to close and the doors were locked with nobody there."
