2006 - 2022



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 Mick

Sirena Mick, mother of three beautiful daughters and four lovely fur babies, comes to us with years of experience handling small animals. 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. Sirena is currently in school working towards earning her veterinarian technician license!

Sidney Eisman

Although Sidney's title is Lead Kennel Tech, she does far more than just that. She can assist with phone calls, getting clients checked in and out of their appointments and assisting the veterinarians during exams! Sidney loves anything involved with large animal and especially enjoys getting to tag along on farm calls. She has four pets at home, Bullet, Cinch, Dori and Rex.



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! 



Hi everyone!! My name is Gandolf and I'm the new resident barn cat! Don't let my size intimidate you as I'm one of the friendliest cats here and will gladly accept any and all pets that you have to offer!
