Zhong, LVT – Veterinary Technician Manager

It took me a little while to finally decide that I wanted to care for and work with animals for the rest of my life. I knew that being a teacher, dentist, or even a scientist would leave me unsatisfied and unfulfilled. Working as an intern in two wildlife rehabilitation centers confirmed that I could not do anything else. Now as a licensed veterinary technician, I am whole and always excited to go to work and continue to help owners and animals alike. Although I can no longer practice wildlife rehabilitation due to my busy schedule with work, my cats, and my saltwater and freshwater fish tanks, I am at least able to consult with other wildlife rehabilitators on cases when they need advice.
