Amber Taylor, Veterinary Technician

California native Amber Taylor recalls growing up with lots of animals all around her, including the injured ones she brought home for care. At age five, the local veterinarian let her “assist” him during a visit and she was hooked on being a vet herself.

She joined North Kenilworth Veterinary Care in the spring of 2011 as a veterinary technician, assisting the doctors in medical and surgical procedures. She loves all aspects of her job and believes that the staff at North Kenilworth has an extraordinary passion for animals which, in turn, is demonstrated by the high quality of patient care. Amber is a versatile employee who is often called upon to fix and maintain items around the office because of her power tool skills!

Off-duty, Amber enjoys hiking, camping, four-wheeling, shooting, and exploring old ghost towns and ancient mine ruins. Her pet family includes Lowrider Larry the Basset Hound, Pitbulls Koda and Macie Grey, and Jersey the lab-mix. She also has five cats and an Amazon parrot.
