Dr Janet Truong

Dr Janet Truong graduated in 2012 with a Bachelor of Veterinary Science from the University of Sydney. Following graduation, she worked for three and a half years at a small animal and exotic hospital in Newcastle where she was able to build her knowledge and gain much experience with all creatures, feathered, furred, and scaled.  However, Sydney was calling, and she was fortunate enough to gain a 12-month internship with the amazing team here at the Avian, Reptile and Exotic Pet Hospital in 2016. When her 12 months were up, she was offered a continuing position as a clinician at the hospital, and it was an opportunity too good to refuse. She feels very fortunate to be afforded the opportunity to work with such a wide array of animals, both pets and wildlife, here at AREPH.
