Eric Swanson, COO, Sunfed & Humboldt Finest Farms

Our Group has been using Anresco Laboratories for the past two years and have always been completely satisfied with their performance. They do an excellent job, are always punctual, and offer the most reliable results of any California cannabis testing laboratory. We have on occasion requested special parameters for testing, short cycle turn around, result verification amongst other non-schedule support needs and Anresco Laboratories staff has always jumped through hoops to accommodate and find solutions to our business needs. I could not be happier or more confident in a group, than what I am with Anresco Laboratories.

Quality and safety is paramount for us here at Kiva Confections. We chose Anresco out of dozens of laboratories because of the reliability of their results, the professionalism of their analysts, and their flexibility with meeting our shifting deadlines. We elect for Anresco’s Pesticide Plus package, which includes more pesticides at lower limits of detection than any other cannabis testing lab in California. Anresco is a true partner to Kiva, and with their help we are able to produce the safest, most consistent and delicious cannabis infused products on the market.

Kim Pedley

I genuinely appreciated how I was treated by all the staff at Anresco. As a small, first time product producer, regulations can be confusing. Everyone made me feel comfortable asking questions, gave appropriate and candid answers, and provided explanations where needed. I would (and have several times) reommend Anresco Labs.

Armando Crespo

As an international confectionery vendor we ship over 600 full truckloads of product to the USA every year. We use many crossing points and we’ve partnered with ANRESCO as their customer service is extraordinary, their understanding of our needs is immediately understood, they guide us through the whole process and a bi-lingual staff facilitates our response to the FDA authorities in a timely manner.
