I made an appointment online. Arrived to find this in the CVS plaza. It is on the opposite end of the place from CVS. Checked in on my phone. Got texted about a minute later to come inside. I was surprised because I was 15 minutes early. David saw me quickly after arriving. Only because this is Yelp, I'll say he is Haitian and we spoke about Haitian food. We both love the food. His wife works there as well. Extremely friendly people. There is a kiosk to check in, but I never used it, I check in online. David hit the vein with one perfect stick. I'm a paramedic, so I feel I understand a bit about this, he did a great job and he was very clean. I had a fantastic experience.

Ok I know this is a sentence someone RARELY says . But hands down BEST bloodwork test ever. I was in the waiting room and was greeted and called in by ALISON who was extremely bubbly, friendly, personable. She makes you feel extremely comfortable, it's like talking to a friend . She's extremely gentle and let me know ok here comes a little pinch and before I know it the tourniquet is taken off, and I had no idea that she was even done. She was so social and talkative throughout the whole entire process that it was extremely calming. I didn't even feel the pinch from the needle. She made the experience the best , and she was so fun and funny that I probably ended staying 5 mins after I was finished just chatting with her. I've had bloodwork plenty of times and this was the BEST experience I've ever had . If your in the area and need bloodwork I HIGHLY RECOMMEND Quest Diagnostic. And ask for Alison . There was no wait , I made my appointment online , I checked in, and within a minute I was called back . The center is SPOTLESS, it's the most clean , pristine Quest I have ever been to, everything was clean , neat, organized . Sanitized. Masks. I wish I could give more then 5 Stars! Tku Alison!

They renovated and updated this location recently making it so much better. The staff is very friendly and work as quickly as they can. They usually have 2 people working so expect a wait on weekends. They are only open until 12 on Saturday and their weekday hours are pretty limited as well. Make an appointment if possible.

Blood work time!

Absolutely worst staff. An issue every single time I went. Kept getting worse and worse. They also need a better system for the wait.
