"Dr. Kammerer has worked with me for a few months as my company has been using their services for Proficiency Testing. Dr. Kammerer has a number of strengths I’d like to share. He has exceptional technical skills. I have run into a few technical issues in regards to a drug panel of ours. He is very knowledgeable and helped facilitate the problem. The “specimens” we have received work well and are very pleased with Professional Toxicology Services. Everyone is accommodating and the quality of products is excellent. I would highly recommend Professional Toxicology Services."
"Professional Toxicology Services, Inc. is one of the few companies that I deal with that live up to the “Professional” in their name. All of my purchase orders are processed and delivered to me without ever an error and well within the time frame requested. Communication is another strong point from this vendor. They also “special handle” label requirements that we need and are perfect at letting me know when labels are running low to assure continued supply without disruption. Again, one of my favorite and dependable vendors."
"I have been doing business with Professional Toxicology Services, Inc. since 2004. Over these years Protox has and remains very professional, accurate and dependable with our Blind Specimen Testing program. At the end of each year after calculations has been made all we have to do is contact Protox and the process begins all over again without any problems. I would highly recommend Professional Toxicology Services, Inc. to anyone in the drug testing business!"
"We have been very pleased with the wonderful relationship that has been built between our two companies over several years and plan for that to continue into the future! Prompt service and quick response to our purchasing needs as well as technical support on the bluing products for some of our customer’s questions has been truly appreciated. The people at Protox are jewels to deal with and found them to be more than willing to go the extra mile!"
