Sad and pathetic lobby.
Angela C.

I hate Quest now. Expecting customer service? Forget it. They've now turned all the offices into prison like rooms with grey walls and kiosks to check in. There's no way to get help if you need it unless you can catch an employee when they come out to call someone for their turn. Recently I booked both myself and my son for appointments at the same date/time. I checked in online and didn't realize it only checked in myself. I asked the staff member when she called me to make sure my son was next and she said she would check after she finished with me. Once she did, she said he wasn't checked in and I had to go back outside to the kiosk to check him in. By the time this happened, it said his appointment time has passed and it cancelled his appointment and he would have to wait as a walk in (30-60 min wait). I ended up having to make another appointment for him for another day. We arrived on time but still had to wait 25 min for him to be seen. Unfortunately I am at the mercy of this clinic as they have the monopoly for bloodwork services that is covered by my insurance. One star for the nice lady who helped us. She was quick and efficient.

The workers here have thee WORST attitude! Not welcoming at all. Their approach to patients when they ask questions is very unprofessional and unwelcoming. If I didn't have to have blood results by Tuesday I would have walked up and gone somewhere else. They need better staff.

I know many places are given a few stars. But the reason for 5 is because l made an appt; got in and out literally within 10 min of checking in. Although they are short staffed, l was still able to do my lab work in a jiffy.

Don't miss this hidden sign!

Lab corp discriminates against minorities and the treatment that is give at the Covina location is…read morenot acceptable. I have spoken to the District Manager Christina couple of times. She has communicated that there is not a bigger location to accommodate this community. They closed the location in West Covina and opened one in Baldwin park. I have to drive my parents further and further from their home because you cannot secure a location that serves the area that they reside in. That is an excuse. There is no posible way you are going to tell me that there is no other location. You have your clients wait upstairs then they are brought downstairs to the basement to wait again. In the basement there is a maximum occupancy of 29 people but the tiny lobby is full at 14 seats. There is no ventilation. You are in extreme close proximity to others. At the very least put an air purifier. The employees at this location are always moody. They look as upset and dissatisfied as the clients they serve. They communicate with the tech upstairs via a walkie talkie that is getting paid as a door monitor. So you charge the insurance of these customers the same as any other city and you give the ridiculous excuse that you can't find another location. That is a flat out lie. You do it because not enough people complain. Because as minorities we are complacent and we traditionally have accepted less. You know this and take advantage of it. Our time is irrelevant to you. You keep maximizing on the amount of money you make per location and we just keep waiting. No regard for our time or the conditions in which we wait. Every time I come here we wait over an hour and a half. YOU HAVE THE CLIENTS TO SUPPORT A BIGGER LOCATION. Please give this community the respect they deserve. Stop ignoring the very apparent need and dismissing it. I am tiered of seeing how you treat people depending on location and demographics. You should be ashamed of this very clear fact. Stop ignoring it! This community deserves better.

Pinnacle Laboratories offers its clients Quick Turn Around Time, Supplies and Helpful Staff…read more Pinnacle Laboratories continues to grow its capabilities as a competitive lab which means our scope also grows. We are very satisfied with Pinnacle Laboratories as they serve our clients' analytical needs. We are grateful that Amber reached out as we were soft searching for a nearby new lab to send out work to. Thanks Amber!
