Lisa Preston
DVM - Owner

Dr. Lisa Preston graduated from Purdue way back in 1988! She is a “Regionite” and grew up in Highland. After graduation, she worked at the Calumet Emergency Veterinary Clinic and also did relief work at various local clinics. She started working at St. John part-time in 1989 and full-time in 1995. Dr. Preston became part owner of the clinic with Dr. Dave Austin in 1999 as they planned a large expansion of the then small clinic.

Dr. Preston is very proud of the growth and expansion of St. John Animal Clinic over the years. “We have kept up with advances in veterinary medicine with state-of-the-art equipment and a beautiful building.  This enabled us to hire many top-notch veterinarians and staff who have contributed to this being a Best of the Region Winner for many years. The daily collaboration between veterinarians really contributes to the high quality care we are able to offer.”

She truly looks at practice as a partnership between the client, pet and veterinarian. The more involved and educated the client is about their animal, the better they can make choices regarding care. She welcomes questions and discussions and sometimes even learns from her clients. Dr. Preston takes her time working with scared and reactive pets and has earned the nick-name “the cat whisperer” for her ability to work with fearful and fearless felines. Dr.  Preston has a special interest in acupuncture and has used it with success, especially for arthritis pain and intervertebral disc disease.

Dr. Preston is married and has two grown children, two cats and two dogs- all rescues (except the children 😊). She enjoys cycling, hot yoga, and is trying to like working out at the gym. She has a passion for adventure. Given the opportunity she will kayak, snorkel, and zipline among other outdoor activities.  A few years back she hiked and camped in the Grand Canyon to see the amazing Havasupi village and waterfalls. She loves planning vacations, especially oceanside, to rest and recharge.

In the final stretch of veterinary school, the owner’s offered Dr. Dunn a position as an associate. She loves the preventative medicine aspect of office visits as well as surgery and every puppy and kitten that walks through the door. One of Dr. Dunn's most rewarding moment as a vet was after a long foreign body surgery, the owner was so thankful that it made the very long, stressful day worth it. Dr. Dunn enjoys discussing animal behavior in order to help owners better understand their animals and live happily together. Dr. Dunn is currently a member of the following organizations: AVMA and IVMA.

Emily received her Associate degree in Applied Science in Veterinary Technology from Joliet Junior College in 2009. While there, she was an active member of the Veterinary Technology Club.

St. John Animal Clinic was lucky that when Emily was finishing up her externship at another clinic she came to us eager and ready to be a part of the team. She’s been a perfect piece in the SJAC puzzle since.

Her own fur babies include 2 pitties named Mia and Yukon. But if you ask her about her most exotic animals she’s worked with she’ll probably tell you her kids!(On a serious note she had owned several exotic species including an iguana, turtle, and a tortoise!)

Outside of working with animals Emily enjoys reading and attending supercross races with her husband. Now that their 3 young children are getting older she and her husband are enjoying getting back into camping. Fun facts about Emily: she is obsessed with polka dots, and of course turtles!

Jessica Bates
RVT

Before deciding to fully immerse herself in the animal world, Jess received an Associates's in Early Childhood Education and a Bachelor in Elementary Education from Purdue University Calumet. Her journey with veterinary medicine, and us, started here when she needed a job while finishing her degree.

Throughout her time teaching, she continued to work as an assistant at SJAC (where we’ve been proud to have her on the team since!), but after teaching 6th-grade science for a year she felt she wasn’t spending enough time working with animals. Between her love for animals and her love for the science behind veterinary medicine, she was compelled to go back to school again and received her Associate in Veterinary Technology from Penn Foster in 2018.

Her four-legged children include Scout an American Bulldog/Boxer mix, and 3 kitties: Scar, a Japanese Bobtail, Clark a domestic shorthair, and her newest addition Cosmo, a domestic shorthair.

She is also a single mom to 3 two-legged children that she is proud to have raised while attending the veterinary technician program and also working full time. In her spare time, she takes her children to the bowling leagues and on camping and hiking trips at state parks.

BS, RVT

Shannon Nowak-Johnson is an RVT here at SJAC. She graduated from Purdue University Calumet with a BS in biology and then continued her education at Fox College where she obtained her degree to take the national exam to become a Registered Veterinarian Technician.

One of Shannon's favorite things about her profession is not only working with the fur babies but helping comfort our human friends as well!

She began her employment with SJAC in 2020, right before the pandemic began! She loves working with her SJAC family and getting to know her clients and patients!

When she clocks out after her busy day, she loves going home to her "zoo." Her 5 cats (Fireball, Whiskey, Riot, JBell, and Beanie), as well as her 2 dogs (Ace and Hazel), give her reasons to smile all the time. Of course, being the animal lover she is, if she could have one superpower it would be the ability to talk to animals. What else could possibly compare?

Clinic Mascot


<strong>MEET OUR HERBIE!</strong>  photo

MEET OUR HERBIE!

I have thoroughly enjoyed my time being the clinic mascot; however, with the recent remodel of the clinic, I was able to find my retirement home at Dr. Cooper’s.  I do miss hiding in the e-collars and sitting on all the laptops, as well as moseying into some of the exam rooms.  In my retirement I get to enjoy napping in various sun locations, playing hide and seek with the kids, chasing the laser light, and hanging out by the pool.  I have even grown to love the new kitten, and do really like snuggling with him…the dog is another story.  I have even trimmed down some, since it’s harder to fool this family into thinking no one fed me!
