Hi guys! My name is Zelda. I'm the smallest member of the HVHC team. Sadly, something happened to my mom before I was even weaned, so I had to learn to survive on my own until Dr. Amy took me in! You will probably see me out and about playing with my brother Merlin!

Sirena's hands-on training in caring for small animals at the local animal shelter has given her a great deal of insight in animal handling and her compassion for animals knows no boundaries.


Mercedes Hennis

When she's not working, she loves spending time with her dogs, Eevee, Gypsy and June, as well as her cat, Layla. Mercedes' favorite part of being a vet tech is getting to help with surgeries and performing dentals!



My name is Daisy, but I prefer to be referred to as the queen of the office! I do enjoy being loved on, but only on my terms. You may see me with colored toenails - this is because I can be naughty and scratch things I shouldn't, so the humans here put these pesky nail caps on. 



Hello everybody! My name is Merlin, and I am the newest member of the Heartland team. I may be the friendliest kitty here and absolutely love ALL of the attention! I enjoy spending my days wandering around finding anyone who will pet me, including clients who are here for appointments. Be careful, I'm sneaky and will dart outside if you don't watch me closely!
