Veterinary Assistants

Megan McKinney

Megan finished at Penn Foster with her career diploma as a veterinarian assistant in 2012 and she’s been working in the veterinary health field for the past year and a half. She has three furry family members— a mixed breed dog named Buzz, Colby a Beagle and Lyla a Chihuahua mix. She lives in Sheridan with son Cameron.

Megan loves all animals but especially pigs, describing them as “super cute” with “mellow (for the most part)” personalities. Her affection for pigs grew throughout the decade she spent showing them in 4H, a tradition that carries on today with her son.



Being raised on a farm fueled my love for animals from a very early age. I knew I wanted to work with animals as a career. I grew up riding horses and competing in 3 day events while also competing dogs in agility and obedience.

I started my career in the grooming industry in 2009. I was trained by some of the best people in the industry and had positive influences around me constantly which gave a strong and confident start. My first dog grooming competition was in 2018 and I won first place with my Brussels griffon in open purebred freestyle. It was an amazing experience and I plan to continue to compete. Seeing all different types of dogs and cats on a daily basis makes my love for grooming grow more and more each day. When I see clients ecstatic reactions to their pets haircut brings me great joy. There are endless options of different haircut types and I’m always eager to please.

When I not pampering pets, I enjoy taking care of my many orchid species and hybrids. I am an avid orchid enthusiast and enjoy going to orchid shows and maintaining my collection.



Kristina grew up in the country and has had animals her whole life including many exotics. She enjoys rescuing and rehabilitation for many types of animals. She lives in the Carmel area with her wonderful husband and two daughters. She says she has a small zoo at home with her cat, Tiberius and may exotics.
