Very Professional and extremely patient

The staff at this lab was very helpful with my contamination problem. I'm not a chemist and needed help figuring out what I needed to have done to satisfy the regulator I was dealing with. Everyone at the lab from the chemists to the bookkeeper took the time to listen to my problem and point me in the right direction. I was impressed with the fact that they didn't try to sell me lab tests that I didn't needed. They even called my regulator to see if some of the testing was really necessary. I highly recommend them.
