Brittany Evans, DVM, MS, DACVIM (Oncology)

Dr. Brittany Evans is originally from a suburb of Philadelphia and found her passion for veterinary medicine at a very young age, when she began volunteering at her local animal shelter. She graduated from Gettysburg College in Pennsylvania earning a Bachelor of Science in Biology in 2010. Dr. Evans then began her veterinary education at St. George’s University in the British West Indies, before transferring and earning her Doctorate of Veterinary Medicine from Oklahoma State University in 2015. It was during her clinical year of veterinary school that Dr. Evans developed a passion for medical oncology. She completed a small animal rotating internship at the University of Missouri in 2016 and a specialty oncology internship at the University of Pennsylvania in 2017. Dr. Evans then relocated to the “other OSU,” The Ohio State University, where she completed a three-year medical oncology residency and earned a Master of Science in Comparative and Veterinary Medicine in 2020. She achieved board certification in small animal medical oncology in 2021.

Dr. Evans’s research interests including canine and feline lymphoma and histiocytic sarcoma. Dr. Evans is a member of the Veterinary Cancer Society (VCS), American Veterinary Medical Association (AVMA) as well as the American College of Veterinary Internal Medicine (ACVIM).

Having a pet diagnosed with cancer is a difficult time for clients and their families. Dr. Evans strives to provide the pet owner with all potential diagnostic and treatment options available to their pet, from multimodal cancer therapy to palliative care. A patient’s quality of life is the most important aspect of guiding therapy, and she will help provide clients with information necessary to make the best possible treatment decisions for the pet and the client.

Dr. Evans moved to Seattle in 2020, which has been a dream of hers since visiting in 2014. She lives with her partner, her two dogs Yoshi and Ripley, and her ragdoll cats Tristan and Ragnar. In her spare time, she is enjoying all that Seattle has to offer including wine tasting, hiking and water activities (kayaking, paddle boarding).

Katherine Robinson, DVM, DACVIM (Oncology)

Katherine Robinson, DVM, DACVIM (Oncology)

Dr. Katherine Robinson is a proud native of Ohio who is excited to call the beautiful Pacific Northwest home once again. She pursued her education across the United States from veterinary school and residency training at the University of Missouri, to internships at the University of Wisconsin and The University of Georgia. After becoming board-certified in oncology, Dr. Robinson started her career in 2018 at a large corporate hospital in Seattle before moving to British Columbia to provide care at an independently owned practice. She very happily relocated back to Seattle in 2022 to work in the oncology department at the Animal Medical Center of Seattle.

Dr. Robinson’s special interests include comparative and translational oncology, the diversity of lymphoproliferative disorders, and histiocytic disease. Her philosophy regarding oncologic care is that cancer treatment should only be pursued if there is the likelihood that it will improve the patient’s quality of life. She is a firm believer in “Just because you can doesn’t mean you should.” Dr. Robinson believes that owners make the best decisions when they are properly informed of treatment options and expected outcomes, and it is her duty to provide that for the owners of her patients in order to be the best advocate for them. Dr. Robinson understands that hearing a diagnosis of cancer in your companion can be scary, and she is committed to making her clients feel comfortable by providing compassionate care and kindness.

When she is not at work, Dr. Robinson enjoys the outdoors by paddle boarding, hiking, savoring a good meal or having a beer on a patio, or just watching the sunset over the mountains from her rooftop. She also enjoys playing basketball, attending concerts, watching sporting events, and traveling. She lives with her partner and their sophisticated Norwegian Forest Cat mix named Sampson.
