    Absolutely wonderful! We had no idea what to expect as we had never done pre-employment drug testing, but they were so warm, friendly, and welcoming to my husband and explained the procedures. The owners were so nice to my young toddler … More son, and very kind to all of us. The procedure was quick, professional, and efficient, and they are so respectful. 10/10! Thank you, Wienhoff!

    I was very happy with this facility for my drug testing that I had to do for nursing school. I originally went to a Quest Diagnostics, and they told me my child couldn’t be there for the testing. The woman at Quest told me I had to leave. … More When I came to Wienhoff, Tracy was so nice and helpful! They got me right in and were very easy to work with, even with my child there. Thank you for making my experience for this process easier and better.

    Robyn and Tracy (sorry if I misspelled) were amazing!! Phenomenal customer service and they made the screening quick and easy for me, when another company couldn’t find a spot for me although I had scheduled an appointment! I appreciated … More them being willing to help me so quickly!! Give them both a RAISE
