Veterinarians

Dr. John Coyne

Dr. John Coyne

Veterinarian, Owner

Dr. John Coyne has been practicing veterinary medicine for over 40 years. He was raised on a farm in Central Illinois, which cultivated his love for animals and inspired him to pursue veterinary medicine. In 1974, he graduated from the University of Illinois College of Veterinary Medicine.

Since then, Dr. Coyne has blazed the proverbial trail, providing the quality of care he believed should be the norm and mentoring many skilled young veterinarians along the way. His dedication to hard work and persistence have led to him now owning and operating multiple animal hospitals throughout Northern Illinois and Northwest Indiana.

Dr. Coyne places special emphasis on wellness care and providing pets with the best quality of life through proactive treatment. Like many pet owners, he regards pets as friends and family members. With that in mind, he believes that pets deserve to have access to timely, quality care whenever they need it, and is willing to go above and beyond to meet their needs.

While the years have gone by, Dr. Coyne’s commitment to pets, pet owners, and his employees, whom he treats like family, has never changed. He continues to innovate and find new ways to help those around him—be it through providing medicine or offering scholarships to veterinary students.

Outside of veterinary medicine, Dr. Coyne is a big fan of University of Illinois athletics and enjoys all Chicago sports. He and his wife, Ruth, have two daughters and four grandchildren.

Dr. Lauren Adduci

Veterinarian

Dr. Lauren Adduci began working for Coyne Veterinary Services in October 2017. She graduated from Purdue Veterinary School in May 2016 and previously worked for an animal shelter/spay and neuter clinic before joining our team. Dr. Adduci believes in preventative care and spaying/neutering to strengthen the human-animal bond and prevent relinquishment to shelters. The more clients know, the better they can understand and care for their pets.

Dr. Adduci has a 10-year-old cat, Alvin, whom she rescued 4 years ago, and a newly rescued dog, Sarge. In her spare time, she enjoys outdoor activities such as fishing and kayaking as well as attending sporting events.

Nicole Steuer, RVT

Nicole Steuer, RVT

Head Technician

What has been your most rewarding moment working with animals?
Those times when pets come in very sick or on emergency & it seems unlikely they’d survive, but after a lot of hospitalization and care they pull through! The real reward though comes from the gratitude of an owner who didn’t think they’d be bringing their pet home…& it melts my heart every time to see that pet run to their owner.

What do you consider your greatest accomplishment at this point in your life?
I have many accomplishments I am proud of, but one that means the most is my dog “Coy”. He is a German Shepard mix. He was very sketchy, had heartworms, ehrlichia, Lyme disease & was malnourished…even though I was actually kinda nervous about this dog…I kept him. I treated him & handled him everyday! It’s been 2 years & he is such a good dog! He was just so scared of everything and everyone…I don’t think he was ever socialized…it’s crazy how much he has changed & how he loves everyone’s attention now!

What’s your favorite comfort food?
Potatoes

Advice to pet owners?
To research what pet you’re about to get, where you’re getting it from & if it’s a right fit for you. Pets can be very expensive & certain pets/breeds can come with a lot of issues & needs. It is very unfair to an animal that ends up in the wrong type of family & now is stressed due to the environment, children, lack of play time or is not taken care of due to financial issues. On the flip side…it’s always awesome to see those dedicated owners that get a new pet, but when it ends up sick they do anything they can…instead of just not treating it or dumping it.

What is your biggest fear?
Spiders and bats. Even looking at them makes me a little nervous!

Most unusual pet you’ve owned?
My mom found a praying mantis on a really cold fall day (she was not gonna make it another week) so she brought her inside & made a whole set up for her, fed her, researched her & gave her a nice “bug” environment…she ended up living for months! We were all so attached, her picture still hangs on the fridge! Her name was “Bug.”

If you could give one piece of advice to pet owners, what would it be?

3 things people might be surprised to know about you?

Favorite quote about animals?
“Sometimes all you need in life is to lay on the floor with a dog…or 10.”
