“Nepenthe provides impeccable service! I want to say first that we have no regrets for having switched to Nepenthe. The Nepenthe portal makes ordering tests and tracking results so much easier. David and Leo have been amazing with setting up and support, they respond immediately. David helped us with our EHR ReliaTrax to get things connected, it was basically up and running the same day. I have never had a negative experience when asking questions of the toxicologists at Nepenthe. They have been very helpful, and I have only had to leave a voicemail once or twice in three years and they called me right back. We are very happy with Nepenthe Laboratory Services.”

“We have been working with Nepenthe for nearly five years and have been extremely satisfied with the service they provide—not only from the lab itself, but also from the reps David and Justin. We receive test results in a timely fashion, and we have heard nothing but good things from our patients regarding Nepenthe customer service, especially billing support. Whenever I have a specific Nepenthe-related need, David responds literally immediately with an answer. We really appreciate the fact that they are a local lab, and highly recommend Nepenthe lab services to our colleagues in Oregon and Washington.”
