Veterinarian

Born in London, England, Dr. Louise Rathjen has lived in multiple cities across the U.S. before pursuing her veterinary degree at Western University of Health Sciences. She was selected for a highly competitive internship at VCA West Los Angeles Animal Hospital, one of the top programs in the country. With a deep passion for senior pets and end-of-life care, Dr. Rathjen founded her own practice, which grew to serve families throughout the Bay Area. After selling the practice to spend more time with her family, she returned to general practice, where she now enjoys treating patients of all ages—from playful puppies and kittens to her beloved geriatric patients. Her focus remains on quality of life, pain management, and compassionate care. Dr. Rathjen lives in Belvedere with her husband, two children, three cats, and three dogs. She also has a horse, Tigger, stabled in Sonoma, where she rides hunter jumper. When she’s not in the clinic, you’ll likely find her with her family, at the barn, or off exploring new places.
