Terrible, terrible. terrible. 10 people in the waiting room all screaming and complaining that they had appointments hours ago and nobody to take them. It's a disaster. Avoid at all costs.

terrible. been here numerous times for care and interview verification. this site in Petaluma is so terrible they have a laminated "we had an emergency" on the front of the door. This is the 5th time I have observed this over the years. they should shut this place down and refer everyone to Lab Corp. much better facility that employs people who did not attend clown school.

The result of my bloodwork yesterday at  Quest Diagnostics in Petaluma. WTH?

See all

One of the male lab techs is a bully and not capable of communicating the needs of the lab to provide service.

Clean facility, professional staff, easy parking. Point of advice schedule an appointment as this can result is long delays.

This is the grossest place I've ever had my blood drawn. The waiting room is tiny, dingy, and…read morepacked with sick people because they take walk-ins along with appointments. It feels outdated and unsanitary. The receptionist was harried but polite, but honestly, the fact that she and the phlebotomists are forced to work in such a cramped, depressing space is unhealthy and downright disrespectful to them. The only reason I'm giving this dump three stars is because of Chris, the absolute gem of a phlebotomist who works there. She's smart, funny, and hands-down the most professional phlebotomist I've ever met. She actually made the whole miserable experience fun. LabCorp, pay this woman more! And while you're at it, stop being a bottom-line-obsessed, corporate nightmare and invest in your patients and your employees. How hard would it be to enlarge the waiting room, slap on some paint, and throw in a couple of plants so it doesn't feel like a forgotten corner of a mental hospital from the '80s? Do better.

Impossible to make an appointment for a simple blood test. The computer access was frozen for two…read moredays. And any phone number I was able to access led be back to the frozen appointment scheduling. As an alternative I contacted Quest a testing facility in Petaluma where I live. I was able to access a phone number over the internet. I called the number and was quickly connected to a human who was able to answer my questions, re availabe appointments, and insurance coverage. I will be staying away from labcorp.
