We have been there twice for labwork and both times we didn’t have an appointment. Both times we were in/​out in less than 15 mins. The employees were all very friendly.

An appointment is a must.
When I got there 5 minutes early there were 4 people in the waiting room.
I went to the head of the line! In and out in 15 minutes!

They didnt answer the phone at 8am and altho it said leave a message and theyd cb i rec. No call. Got here 15m before appt only to be greeted by a empty front desk. Then the gal came out and was very rude and unfriendly. Didnt want to answer my questions and said sit down we will get to you– i decided to wait until 5min padt my appt time then im leaving and going to Brentwood where they have a friendly disposition snd are mire than happy to answer your questions… i wont be back here. They got a one star because of the location.
