Christina Ruffer

Regional Director of Operations

Christina started working in the veterinary industry 17 years ago, and her passion for pets and people flourished the moment she walked in the door at her first veterinary job. She enjoyed the daily routine of working in the kennel, assisting clients and pets, working at the front desk, managing inventory, and managing staff at her local veterinary hospital. After learning multiple veterinary software systems, Christina started to consult and work with other veterinary hospitals to teach them how to properly setup and use their systems. Christina started with American Veterinary Group in May 2016 and has quickly developed bonds with each hospital, working hand in hand with each team. It is difficult to learn a new software system, but Christina makes sure each staff is confident in their training and their ability to provide excellent customer service in the process.
