The staff was professional(not friendly, personal preference) and took a very long time for me to do a pre-employment drug test(45 minutes total; 40 minute wait, 5 minutes to complete the test). There were only 2 people ahead of me and one had already been waiting for 45 minutes and the other for about 30 minutes. I would be sure you prepare to spend approx. 1 hour here if you are doing a pre-employment test. They do not take appointments.
