I actually run the day-to-day operation at the hospital, or at least I like to think so!

  • Kelsey - Veterinary Assistant

    Born and raised in Georgia. I have always wanted to help animals even when I was little, trying to convince my parents to take in all the stray animals we see. I got into the veterinary field in 2020 and have loved every second of it. I have 2 dogs, Bella (6 years old) and Brandi (4 years old). When I am not working, I am either hanging out with my family and my boyfriend or finding something to do outdoors. Whether it’s fishing or going to Braves games or when I’m feeling lazy just laying around watching Netflix.  

  • Mackenzie - Veterinary Assistant

     I was born in Montana but raised in Las Vegas, Nevada. How did I end up in Georgia? Well, I wanted to be closer to my family. Growing up having dogs, I knew from a young age this is the field I wanted to work in. I have been working with animals since graduating high school in 2016. Started as a pet sitter moving to boarding and now here as a veterinary assistant. I wouldn’t be here doing what I love to do if it wasn’t for the love and support from my family.

    I have two dogs of my own one male named Rocky (a toy fox terrier and according to his DNA test a hint of Bull mastiff) and one female named Dixie (a Dachshund mix). I do enjoy watching baseball and I love watching football. My favorite baseball team is definitely the Braves, but my favorite football team is Tennessee which may come to a surprise since I have never lived in Tennessee.
