Meet Our Veterinarians and Team Members

Our veterinarians and supporting team members turned their love of animals into an opportunity to help loving owners care for their four-legged companions. They share the philosophy that owners need just as much care as their pets, while bringing their own unique experiences and perspectives to the practice. Read their bios to learn more about them!


Kalynn Koza, DVM

What is your educational and work background?

I completed my undergraduate degree from Kansas State University in Sociology and International Studies in 2008. I graduated from the University of Illinois in 2015 with a doctorate in Veterinary Medicine. Since graduating, I have been practicing in the small animal hospital setting seeing dogs, cats, rabbits, rodents, and guinea pigs.

What made you decide to become a vet?

Like many others, it was my childhood dream to become a veterinarian; as I matured, I discovered it perfectly merges my love for animals and my passion for science.

Why did you decide to join the Companion team?

Companion’s mission statement mirrors my belief to practice high quality medicine with a compassionate team.

What is the best thing about being a vet?

I love seeing my patient back after the treatments I have instituted and watching how happy both the pets and owners are at the progress they have made. It makes me feel as though I am truly making a difference in this world.

What is one of the most common problems you’ve encountered in pets you treat?

Dental disease. It surprises many owners to learn how quickly our pets teeth can decay and how a little home care can go a long way in preventing infection and pain.

Soft tissue surgery, internal medicine, and exotic small mammal medicine (rabbit, rodent, & guinea pig)

Support Team


Laurie, Hospital Manager

Hi, my name is Laurie and I am very excited to be a part of Companion Animal Hospital.

I have been a Veterinary Technician for 17 years now and has been managing the last 11 years.  I could not imagine myself doing anything else as being a patient advocate is my passion; the sense of pride I get from helping pets and their families makes it all worthwhile.

When I am not at work, I like to spend time with my family and friends and go to agility and scent training classes with my Pitbull, Hope.  I also have a cat named Hayden.

I look forward to meeting and working with you and your pets!

Hi, I'm Stevie! I've happily been a technician for about 4 years, however I've been working with animals since I was 14. I'm forever filled with  bliss knowing I get to wake up every morning doing what I love, helping you and your furry family members.

Nicky, veterinary assistant

Hello, my name is Nicky! I joined the Companion family in September 2020. I graduated from Southern Illinois University with a Bachelor of Science in Zoology, with an emphasis in Wildlife Biology and Conservation.  I have been in the veterinary field for a year now. My interest in the field increased significantly when I was working as an Animal Cruelty Investigator for the Humane Society of Missouri in St. Louis. I then worked at an animal emergency clinic and regular veterinary practice 2 years after. I currently aim to improve my skills and attend further schooling to become a veterinarian. I have two dogs, a yellow lab/pit mix named Fitzpatrick, and a black lab named Roxanne. I also have an American Sable rabbit named Bolin. Other than animals, I also love playing video games, listening to music, and creating art! I look forward to working with you to provide the best care for your pet!

Gilly, Pet Groomer

Hi I'm Gilly and I have been grooming in the Chicagoland area for over 20 years and can’t imagine doing anything else! I love making your furry family member look and feel their best. One of my favorite parts about grooming is the bonds I form between your pet and getting to know all of you! I have always been an animal lover, and remember wanting a dog when I was a young girl - it only makes sense that this became my profession. I look forward to getting to know you and your furry family members!
