Brittany Atkinson - Veterinary Technician

Prior to becoming a veterinary technician, Brittany earned a degree in Anthropology with a minor in Biology from Northern Arizona University. During her undergraduate years, she interned at Chimp Haven in Shreveport, Louisiana, working with chimpanzees that have been retired from medical research. This work required her to quickly learn how to read chimpanzee body language, decipher the meaning of different vocalizations, and in turn reciprocate communication effectively. Brittany has been working as a veterinary technician for nearly eight years. She is currently in school working toward her associate’s degree and certification in veterinary technology, and will complete her coursework at the end of 2018, at which point she will begin working toward her VTS in behavior.

Brittany’s passion for behavior was catalyzed seven years ago with the adoption of her dog Gru. Gru came to Brittany at twelve weeks old with both of his left legs broken after having been attacked on multiple occasions by another dog. The emotional scars of those traumas, in addition to his physical inability to be well socialized as a puppy left Gru lacking in the important life skills he would need to confidently live in the world around him. When it became obvious that he needed more than just basic obedience training and exposure to other people, animals, and environments, Brittany sought the help of Dr. Gail Stevenson at Veterinary Specialty Center of Tucson who had a special interest in behavioral medicine. Dr. Stevenson continued to mentor Brittany long after Gru ceased to be her patient. Prior to Dr. Stevenson's retirement in December of 2015, Brittany dedicated several months to shadowing her practice.

In addition to spearheading her own behavior consulting program at her previous practice in Sierra Vista, Brittany has been a member of the Society for Veterinary Behavior Technicians and has attended the Clinical Animal Behavior Conference annually since 2014. She currently serves on the Sponsorship Committee for the Clinical Animal Behavior Conference.
