Lynnann W.

I was a walk in for blood work for a physical. It was around 0900 in the morning. I waited less than five minutes and was called back. The woman was kind, efficient, and the blood draw was painless without bruising. That's a "win" for me. Covid protocols were everywhere; you can even choose to wait outside the building if it makes you more comfortable. Without hesitation I would choose to go here again when needed.

Easy, good blood draw and I still bruised up. Rude.

They only have one room operating and they are fully booked for several weeks. It is not very convenient at all.

There is absolutely zero customer service from this company. Do not try and call them or speak to a person it will not happen.

They would not take the standby customer who is the only person in the waiting room. They rather stay idle.....

Terrible service. Long wait and have no compassion for your situation. They are just looking for a reason to leave early.

Had an appointment at 9:40 and was out by 9:52. Make an appointment online, don't call. Walk ins are hit or miss.

My son has special needs and this is one of the very few Quest locations that I trust. We've had so…read moremany awful experiences that we are willing to drive for a good phlebotomist- this location has never let me down. We had Vanessa today and she was absolutely amazing. She got the poke on the first try and even though we needed to get several vials, she stayed patient and calm the entire time. It was one of the least stressful blood draws we've had because of her expertise.

Quest Diagnostics in Foothill Ranch is located in the Hoag Medical Building. You can enter through…read morethe Hoag Urgent Care Center doors and find them immediately to your right. This was my first visit to Quest Diagnostics in a long time. I had been going to a different lab company for the last several years since they had some long term employees that could get my veins. I was honestly a bit nervous to go to Quest and encounter someone who hadn't worked with me before. Check-ins are done at the kiosk. It's easy to do and was literally just one to two minutes at most. I had an appointment for 1:00 pm and was called back less than five minutes later. Unfortunately for me, only one of my Dr's lab orders went through their system, so I had to get bumped out of my appointment. I called the MD office for them to re-send the orders and ended up being a "walk-in" but since they weren't super busy, I was called back again after ten minutes. The phlebotomist who worked with me was, Gervon? I hope I got that right. I meant to write his name down but got side tracked. Anyway, he was great. He was progressional, and easily without hesitation, able to find a vein on me. The poke was painless. It was so fast. Gervon, filled several vials and was done before I even realized he was switching them out. I will definitely be asking for him during future visits. I was very happy from start to finish. Thank you for the pain free lab draw, Gervon. I really appreciate you.
