Crown Refining is a well-respected business that has serviced Dentist and Dental Laboratories for many years. We are a small family owned company with 3 of the owners working their own territories and the fourth owner managing the office, which means we can pay more to our clients, as our overhead in the sales area is minimal. Our biggest concentration of work is in Southern California but we also service Northern California, Washington State, Texas and Arizona with the help of our sales reps. We also have several clients in other states. We pride ourselves in acquiring clients for life.
