Kim H is incredible. She’s super friendly, gives you great instructions and ensures that the tests are done right. She’s been there for 40 years and i was the highlight of my day! Keep up the great work Kim! You are appreciated!!

I just finished my drug test for nursing and it was good, I will say to have a 40 minute window as i finished my drug test at 1:30pm but I had an appointment at 1:10pm due to the people prior to me having difficulties. Kim helped me get my paperwork and collect my sample and she was super kind!
