Since 1986, through the encouragement of veterinarians, McAllister Software Systems began developing a veterinary software system that evolved into the software known today as AVImark. With the aid of Henry Schein, Inc., AVImark has emerged as the #1 veterinary practice management system with over 8,000 current users and growing. Much of this growth is due to our strong commitment to customer service and value—something you'll readily see when you speak with us the first time.

AVImark is the direct result of thousands of user requests, nudges, and suggestions over the years, so you'll find it specifically tailored to meet the needs of the modern veterinary practice. This help from our loyal customers has helped AVImark continue to maintain the industry's highest customer satisfaction rating.
