    I was waiting in the car for a text message to check in and i got the text message at 8.40am. My appointment was 8.40 am. I checked it through the app and walked in to the clinic. They said they already called my name and i was not there, and made me wait for 45 minutes. They took every one who is appointment was after mine. This is unacceptable. The text message usually comes 15 minutes before the appointment time. Why did the text message came so late. Even if the text message was late. it took me two minutes to walk in to the clinic from my car and they called my name and because i was not there, i have to wait for 45 minutes. This is atrocious!

    My appointment was at 920 they were very quick at getting me in but once in the phlebotomist told me they did not have my orders. Was already on the phone with my doctor because I already had a feeling since multiple people were complaining. My doctor confirmed they send the orders thru my chart since Feb 6 th super disorganized. I work with dme so I’m familiar with the system being used my chart why are they not pulling the orders and uploading them to the accounts before appointments. Will be filing a grievance with my insurance.

    Many of my family members have gone to the FV Quest on Warner for over a decade. We feel like we hit the jackpot every time Hong calls us back! We've all had issues with getting our blood drawn...but never with Mr. Hong!

    I get my labs done every 6 months and always go to this Quest. Hong is my phlebotomist and is always so friendly. His experience in the blood draw process is almost painless. Just a quick prick from the needle and then it's all good. I hope he is my tech for many, many years. Thank you for the great staff at this Quest!
