Take it from our Clients

Group 4

“Some of my favorite people in the world! First and foremost these guys are real scientists. They don't jack you around. They are the only lab that can test, with consistent accuracy, for the amount of product that we produce. The employees are fantastic and I have nothing but good things to say about Cal Ag Labs.”

- Joshua Taylor / Emerald Sky

Group 4

“Robert and the team at CAl Ag Labs are generous, responsive, friendly, transparent, timely, and go above and beyond for their clients. We had an RO water testing issue and Robert took time, on his day off, to do in depth research that eased my anxiety. Upon dropping off product at the Marysville facility, I was offered a tour by Robert. I found the facility to be clean and High-tech. They are just great people and I can honestly say I have developed great friendships which are rare.”

- Dan Marmor / CANN Beverages
