  • Irene Troy, RVT
    Veterinary Nurse

    Irene was born and raised in the Bay Area and has chosen to be surrounded by animals her entire life. She actually majored in English at UC Davis, but it was still no surprise when she became a vet tech 10 years ago. She immediately had an intense passion for the job, which has never left. Irene considers herself to be incredibly lucky to have found a job that allows her to be of service to animals as they have truly enriched her life and changed it for the better. About 5 years ago, she took the steps required to become a RVT so she could continue to grow in her career and best help the animals that she works with. She has gained experience in general practice, emergency medicine, critical care medicine and internal medicine during her time as a technician and she loves the opportunity to work with the exotic animals we see at Oasis Veterinary Hospital.
