  • Janette

    Hi there! My name is Ginny and this human is my momma Janette! She always talks about how she wanted to work with animals since she was young. Out of high school she went to Pima Community College and graduated from the Veterinary Technology Program where she found me! When I got to my new home I had 2 sisters named Autumn and Noel, who mom calls 'kitty cats.' Recently I got a new brother named Tonic, who we call 'Wild Man.'

    Mom joined Acacia Animal Hospital in 2017 and always comes home smelling so interesting. She tells me that she works with exotics and birds but I definitely smell dogs. In mom's free time we sometimes go hiking or visit people but mostly we play in the yard or cuddle on the couch (she tells me I'm the best cuddler). I hope your furry or non-furry baby loves her as much as I do, I know she'll love them!

  • "Woke up on Saturday and my dog wasn't feeling well was having a problem with her ear. Even though she isn't a patient there, I called Acacia and they got her in for an appointment 45 minutes later. The vet tech and the vet were both super kind and gentle with her and answered all my questions. Will definitely put this place on my speed dial!"
