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!


Kim Mellies

Kim was born and raised near Holton, and stayed close to home. She has a CNA degree with a large amount of experience in medical field. All of Kim's free time is spent with her 3 kids, running to and from activities and spending time with family and friends!

Mercedes Hennis


Mercedes Hennis just recently joined our team and brings 6 years worth of vet tech skills and experiences with her! Mercedes is originally from Holton and graduated from Royal Valley in 2012. 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!
