Biography

Dr. Arthur fell in love with both Dr. Doolittle and James Herriot at a young
age, and decided she would spend her life telling the amazing stories of
animals far and wide. She obtained an undergraduate degree in English
from Gettysburg College and just before graduation realized she wasn’t
that great of a writer. She then obtained a second undergrad degree in
Biology and Genetics from CSU with the intent of heading to veterinary
school. Dr. Arthur attended Ross University School of Veterinary Medicine
on the island of St Kitts, completed her clinical year at Texas A&M CVM,
followed by a one year general internship at Kansas State Veterinary
School where she discovered her love of Oncology. A Radiation Oncology
Residency at NC CVM was then completed, followed by board certification.

At that time Dr. Arthur realized she was frustrated with not being able to
treat her patients with everything that they needed, including
chemotherapy. So, she then completed a Medical Oncology Residency at
a private practice outside Phoenix, Arizona. The next six years were spent
back in NC providing medical oncology services at a large private practice
and working with the Duke Comparative Oncology department on several
research projects. An opportunity to return to Colorado came up and Dr.
Arthur and her family moved back to her favorite state five years ago. She
has worked at two private practices in Lafayette and then in Castle Rock
since then. While in Castle Rock, Dr. Arthur realized there was a significant
need for Oncology south of Denver, with clients coming to see her from as
far as New Mexico. Dr. Arthur is joining Moves and helping to develop the
Oncology department to be able to extend oncology services to clients over
a much wider geographical range.

Dr. Arthur’s primary goal as a veterinary oncologist is to be able to provide
an amazing quality of life to patients with cancer, while extending the time
they have with their families. She encourages any owners faced with
cancer in their pets to meet with an oncologist to get all their options
outlined. She is fond of saying that there is almost never a case where

nothing can be done, and there are always options, ranging from the most
intense, to palliative/hospice care.

Dr. Arthur is lucky to have a very supportive husband, two goofy dogs (Lula
Mae and Archie) and two handsome cats (Abner and Melvin), who rule the
home.

    What is a board-certified veterinary oncologist?

    A board-certified veterinary oncologist is a veterinarian who has completed advanced, specialized training in oncology, the study and treatment of cancer in animals, after graduating from veterinary school.

    This training typically includes three to five years of focused education, beginning with a rotating internship across medical and surgical specialties, followed by a residency dedicated specifically to cancer care. During this time, oncologists gain in-depth expertise in cancer diagnosis, treatment planning, chemotherapy, and compassionate long-term management.

    To achieve board certification, veterinary oncologists must pass rigorous examinations and meet publication and training requirements set by the American College of Veterinary Internal Medicine (ACVIM). Veterinarians who complete all requirements earn Diplomate status, which signifies recognized board-certified specialty care in Medical Oncology.
