The staff tells me it is a 30 minute wait. I understand it's busy. But one hour and twenty minutes is a very long time to wait. Especially when you come ready to give a sample. There were not enough chairs and five people had to stand. They need to hire more staff and make more reasonable accommodations for sitting. I tried calling to make an appointment on three separate occasions and no one answered the phones.I tried scheduling an appointment online and it did not work. It said no appointments avaliable. If I did not need a drug screen for work, I would have left. Try to avoid this place if possible.
