The facility is very clean and neat which was good to see. My appointment was quick with no time wasted. You're in, you're out, then you're on your way back home.

So I gave up on them and had to go to another lab. After wasting so much time and gas to go back and forth. Wish I could give them zero (0) stars. I am very disappointed with this lab.

I've gotten my blood taken plenty of times, part of it is because its my job, other parts is because of check ups, blood drawns and what have you. The first person who took my sons blood was horrendous. She missed my son's vein, then started to fish the needle around. My son is 8 and on the thin side. I thought that needle was going to come out of his arm the way she was pushing and shoving it. Finally she gave up and pulled the needle out. She was going to try again and I told her no,and that i had never seen anyone move a needle that much in someone's arm. She got snippy and asked if I wanted someone else to do it. I said yes and she went to get her co worker. As she was on the other room she said that it was because my son had small veins and hadn't had alot of water. Then the other person came up, stuck the needle in and found the vein immediately. She left the needle in as she got the vials of blood she needed. No fuss, no mess. As she was filling things out she was mutterinv "oh, God!" Like I was bothering her. My next action after this is to find her manager and log a complaint.

Another person comes to the desk and calls my name minutes later, proceeds to look at my records in her system and immediately print the lab order and say thanks that's all.

The first tech wasn't trained or confident enough to draw blood. The second tech, Ashley, was rough and poked my baby for an extended time--still failing to collect enough, then claiming the sample was insufficient and discarding it without our consent. When we spoke to the supervisor, Erika, she was rude, dismissive, and wouldn't let us explain. She wrongly assumed this was an immigration‑related test and treated us accordingly, which was completely inappropriate and unprofessional. We had to fight to have the sample sent, and surprise--it met minimum requirements and we got results the next day. If we hadn't stood our ground, our baby would have gone through another unnecessary blood draw. Poorly trained staff, rough handling of an infant, and an arrogant supervisor. Terrible experience. Avoid at all costs.
