Only with appointment. Staff are so busy working they don't have time to check the lobby for people to help check in. I observed another patient help a lady. He earned some kindness rewards in the universe. If you come for standby you will be waiting all day.

It's difficult to make appointments on line which is the only way to contact them . It was an emergency lab request from my Dr.

How does a business never answer their phone?? It goes to voicemail, and a message says they have not set up their mailbox yet. Really??

If you have a family member with a language barrier or just from an older generation, make sure you…read moreschedule an appointment for them on their website and come with them. The front desk staff is not patient or friendly at all to those with tech illiteracy. First of all, the stress of COVID precautions means only 7 patients are allowed at a time in the waiting room. Which is not a bad thing, but it creates a waiting system especially for those without an appointment. Personally, I did not have any problem checking in or waiting to be seen. It was smooth sailing for me. But it really bothers me when our elders and those with a language barrier are treated as second class citizens when the people working there obviously also speak Spanish too, proven because I heard them speak it. Parking was easy and so was finding the place.

The wait here is absolutely ridiculous. There are so many people waiting that there isn't even…read moreanywhere to sit. They definitely need to hire more techs or have better staffing during busy hours. When we arrived, there was only one person drawing blood while also taking care of the front. Another tech eventually came back from break, but instead of helping with the long line of patients, they were in the back chatting while everyone continued to wait. It's extremely frustrating to sit here for hours, especially when you can see how understaffed and unorganized the location is. I completely understand that places get busy, but when patients are waiting this long and there aren't even enough seats, something needs to change.
