    Got there at 7 am when the lab was supposed to be open. They were 2 of us and then ln wasn’t open and then 3 and then 4. 7:22 am and the lab wasn’t still open. THIS IS APPARENTLY TYPICAL. A safeway employee passing by kept apologizing and said this is a FREQUENT OCCURRENCE and asked us to talk to quest about it. This guy whoever he is is NOT HONORING his employer’s contract. We all needed to be at work and got there by appointment and walk in to get our lab work done at 7 am because the business is supposed to open at 7. This is a SHAMEFUL and DISAPPOINTING business practice. Someone close to me had similar experience not long ago but I thought I’d give it a try as they are advertised to open at 7 am. I imagine it would take another 15 mins at least to get set up. Two of us waiting tried calling the numbers. It rang to voicemail which was full. The voicemail also stated that they open at 7 am with a 1 hr break at noon!!! How do you come late to work REGULARLY and have an hour break for a 7 hr work day? What is mind-boggling to me is how this IRRESPONSIBLE EMPLOYEE still has this job being a regular occurrence????!!!

    This location is the worst. Twice had appointment and twice they cancelled without informing us so traveled 40 min EACH way for nothing. Don't choose this location

    Very clean and conveniently located. Hardly any wait time as a walk-in. CJ was was so professional and an expert of his craft. I am usually a "hard stick" but he made it so easy.
