Dr. Scott Petereit
Since graduating from the University of Illinois College of Veterinary Medicine in 1991, Dr. Petereit brings over 25 years of clinical small animal medical experience to Companion Animal Hospital Mount Prospect. His interests include soft tissue surgery and internal medicine, and employing diagnostic modalities of ultrasound and endoscopy. He works hard to thoroughly educate pet owners about their pet’s care in order to help them make the best decisions regarding their well-being. Dr. Petereit is a member of the American Animal Hospital Association (AAHA), the American Veterinary Medical Association (AVMA), and the Illinois and Wisconsin Veterinary Medical Associations.
Dr. Petereit volunteers his time to provide veterinary care to homeless pets at The Buddy Foundation, a no-kill shelter in Arlington Heights, IL. When he’s not helping pets he spends time with his wife, their 3 children, and the family dog, Tyler. In his free time, Dr. Petereit enjoys the outdoors and loves fishing, hiking, and snowboarding.
I always loved the sciences and have raised one type of animal or another throughout my life. As a kid I hatched and raised chickens and pigeons and even had a pheasant as a pet. I also had salamanders, turtles, gerbils, guinea pigs, and even raccoon kits at one time. I got my father to take me to buy a dog with money I had been saving for two years when I was nine years old. When it was time to plan a career, veterinary medicine was the obvious choice.
Generally, when you can help a pet that is truly suffering or ill and help heal their illness to return them to the arms of their happy owners...this is always a big reward.
My second career choice was to be involved in some sort of wildlife management career. Perhaps I might be in this field now.
Maggots...yuck! Unfortunately, I have seen some animals that were so debilitated that their wounds were infested with maggots. I have nightmares about maggots.
This is still a work in progress, since I am still raising 3 children with my wife. Years from now, I hope I can look back and say that this was my greatest accomplishment.
Dental disease and obesity. I see both of these health issues lead to significant disease on a daily basis.
A coatimundi, which is basically South America’s version of a raccoon. In veterinary school, I assisted with a black bear and a Siberian tiger.
I’ve never met a cheeseburger I didn’t like.

- I was charged by a brown bear in Alaska once
- I was a college cheerleader
- I am a pretty good snowboarder
- I can still walk at least 20 yards while doing a handstand
Dr. Jessica Smith
Dr. Smith has been practicing veterinary medicine since she graduated from the University of Wisconsin-Madison in 2004 (Go Badgers). She has a special fondness for wellness care, dentistry, and internal medicine (especially ultrasound) but loves being a “jack of all trades!” When she’s not at work, you can find her with her family which includes her husband Patrick, their children Alex, Nate, and Evelyn, and their dog Cora. In what little spare time Dr. Smith has, she is sneaking in a good book, catching up on movies, or just enjoying the silence.
I was always good at science and math, and when you combine that with my love and respect for the human-animal bond, it was a no-brainer.
Helping L.T. – he was a cat who ate string, and it perforated his intestines. I really didn’t think he would make it during surgery. He definitely had a few rough days afterward, but he made it! And a few months later, I saw his owner who said he went off to college with her daughter. I just remember thinking how great it felt to have been a part of helping give him and his family those memories (and then hoping he wouldn’t gain weight at college).
In my dream world, I would be a movie critic or a National Park Ranger out west. In reality, something more practical like a math teacher.
My family of course!
For cats, it’s being allowed outside unsupervised. It can lead to distress, wounds, and trauma that indoor cats do not have to face. And for dogs, it is being off-leash outside. Every time I hear about a dog hit by a car, I am saddened to realize that it was most likely preventable.

Ice cream. Chocolate. With Oreos on top. Now if you’ll excuse me, I need to go to Culver’s.
- I have been SCUBA diving with countless sharks at the Blue Hole in Belize.
- I love to swim. Every September, I swim a 5K race in Lake Michigan along with other competitions when I have the time.
- I hate mustard. On anything, at any time. Can’t even stand to smell the stuff!
- I could watch nature shows on TV until my eyeballs fall out.
- I am one of those rare people who enjoys what they do for a living.
Dr. Erin Walsh
Dr. Walsh graduated from Purdue University in May 2010 with a degree in Animal Sciences and a minor in Biology. She enjoyed her time at Purdue so much that she stayed for her Doctor of Veterinary Medicine degree as well. She graduated from vet school in 2014 and worked in a small animal clinic in the south suburbs for a year before coming to Companion Animal Hospital.
I was lucky enough to have parents that shared my love of animals. In high school they let me foster for a Beagle rescue. Many of our foster dogs came to us with medical issues, which involved lots of vet visits. During these visits I realized that this was something I would love to be able to do for the rest of my life.
One of my very first cases was a rescue dog that had recently given birth to about 10 puppies and quickly developed a very severe case of mastitis (infection of the mammary glands). She was not doing well initially, but with time and care she made a full recovery and eventually got adopted by a wonderful family. I will always remember that case and how awesome it was to see how much she was progressing with each recheck exam.
I was looking for a clinic that practiced high-quality medicine with modern equipment and a kind staff. After replying to a job posting and then visiting Companion Animal Hospital, it seemed like an easy choice to come work here.
I love the fact that my job allows me to do a little bit of everything. There is such a variety of cases you can see in any given day—wellness exams, dermatology issues, endocrine disorders, orthopedic disease, cardiac disease, etc. Being able to help create individualized treatment plans for each of these patients is very rewarding. Every day is different!
Dental disease, by far!
I had an older diabetic patient that developed a severe case of pancreatitis and was not doing very well despite hospitalization and treatment. She wouldn’t eat or drink anything for several days and was not acting like herself at all. Fortunately, she eventually began to respond to treatment and was able to go home to her owner after about a week in the hospital. She is now living with me due to her owner’s own health issues, and to watch that pup ravenously chow down on her low-fat diet every morning and night is the greatest thing!
I love working with patients with endocrine disorders, especially diabetes. I also enjoy neurology and ophthalmology cases.
In vet school I neutered a spotted genet; it was the sweetest critter.
Of course, I love spending time with my rescue dogs (Zoe, a Maltese; Jojo, a Shih Tzu mix; and our recent addition, Bridey, a Terrier mix). I also enjoy spending time with my husband, Brian. I love reading, exercising, and traveling when I get the opportunity.
People who are inconsiderate to others.
Anywhere with good Mexican food.
Purdue University—it’s always fun to go back to your alma mater.
It’s a Wonderful Life
Dessert, especially ice cream
I am actually not a big sports fan, but I will root for any of the Chicago teams.
- I’m the oldest of 5 kids, and 4 out of 5 of us have degrees from Purdue!
- I have 3 senior rescue dogs, 2 of which are diabetic—and all 3 are deaf!
- I have fostered 30+ dogs for various rescues since high school.
Dr. Sarah Nokes
I graduated with my BA in Biology from Monmouth College in 2009 and received my DVM from Iowa State University in 2019.
Like most veterinarians I've always loved animal since I was a little girl, however I didn't decide to pursue veterinary medicine as a career until my mid-20s. I was working in wildlife research and management but found myself much more interested in the process of treating animals rather than data collection.
I previously worked at Companion as a veterinary assistant for 2 years before I went to vet school. It was an easy decision to come back home 🙂
Aside from working with dogs and cats all day, I love being able to help solve a problem or at least provide guidance and support to owners. I love working with an owner to make the best decision for them and their pets.
Realistically, I would probably still be working in wildlife research and management. Dream world, I would be a film critic.
Dental disease, skin allergies
Cardiology, dermatology, ophthalmology
I spent 6 weeks at the Brookfield Zoo during my clinical year of veterinary school and helped monitor several pregnant pangolins.
Reading, going for walks, yoga, watching movies, traveling.
Silver Linings Playbook.
I love pretty much any type of food but I'd have to say the best thing I ever ate was the barbeque shrimp from Mr. B's Bistro in New Orleans.
1) I'm left handed
2) I've been bitten by an opossum (while working as a wildlife technician)
3) I've hiked the Grand Canyon
Stefanie, Practice Manager
My name is Stefanie, and I joined the Companion Animal Hospital Mount Prospect team as a Veterinary Assistant in July of 2008. I have always had a love for animals, and finding this position at Companion Animal Hospital Mount Prospect was perfect. Not only is it wonderful to encounter so many adorable animals throughout the day, but it is also very rewarding to care for and treat sick pets. When I am not working I am spending my time with my kitties Izzy, Emma, Leonidas, and Maverick. I also enjoy spending my time outdoors camping, hiking, running, or just soaking up the sun. Hope to see you and your adorable pets soon here at Companion Animal Hospital.
Jessica, Professional Pet Groomer
Hi, I'm Jessica. I joined the team back in March of 2010. I became a professionally certified pet groomer in 2001. I pride myself on being able to give pets a low-stress grooming experience and am familiar with most dog and cat breeds. I share my time between grooming here at Companion Animal Hospital Mt. Prospect and at Companion Animal Hospital Vernon Hills. In my off time, I enjoy spending time with my husband and daughter. I have 2 dogs, Teddi Bear and Chloe; and 4 cats, Rascal, Harley, Mocha, and Athena that help keep me busy too. I look forward to meeting you and your pet and giving them a relaxing day at the pet spa!
Ilona, Certified Veterinary Technician
My name is Ilona and I joined the team at Companion Animal Hospital Mount Prospect in April of 2009. I was originally born in Poland and I came to the United States when I was 10 years old. After receiving my Bachelor of Arts degree in Psychology at the University of Illinois at Chicago, I realized that I would rather follow my passion for animals and pursue a career in veterinary medicine. So, I moved out to Denver, CO and attended Bel-Rea Institute of Animal Technology, where I received my Associate of Applied Science degree. I began my career as a Certified Veterinary Technician at CMAH and I really enjoy working at this hospital. When I am not working, I like to spend time with my crazy lab “Max” and his buddy “Kubus.” I also like to watch movies, play my Wii, play tennis, and go skiing during the winter. I look forward to meeting you and hearing all about your wonderful pets!
Greetings! I am so happy to be a member of this excellent and caring team. I have been working in animal hospitals for 18 years. It is so refreshing to be in day practice after almost 10 years at an animal ER. I just love seeing people caring and taking responsibility for their pets’ well-being. It makes me smile!
When I am not at work, I am enjoying the love and companionship of my 3 Himalayans and 2 Siamese cats, my gorgeous and loving Collie, and my quarter horse Palomino mare. Happy trails!
Rachelle, Certified Veterinary Technician
Hello! I’ve loved animals for as long as I can remember, so working at Companion Animal Hospital Mount Prospect is very rewarding and a dream come true! I graduated from the Vet Tech Institute at Fox College in December 2013 and joined the CAH team as a CVT in February of 2015. I have been working in the veterinary field for a little over a year now, and have loved every minute of it! When I’m not at work I enjoy horseback riding, running, playing trivia with my friends, and chilling out at home with my 2 cats, Timone and Davy, and my Wheaton Terrier, Bailey. So stop by soon, I can’t wait to meet you and your fuzzy friends!
Isabella, Veterinary Assistant
Hello, my name is Isabella! I'm currently a student at Palatine High School. My dream after high school is to become a certified vet tech. I love animals and I applied for this job knowing I would be closer to the animals I loved, and also my passion. I own 2 Corgi dogs named Ceasar and Shadow, 2 birds named Cookie and Spike, and a leopard gecko named Tony. When I'm not home with my animals I also like to hang out with my friends, play volleyball, watch movies, and go shopping. I'm looking forward to meeting your pets!
Kate, Veterinary Assistant
Hi, my name is Kate. I received my Veterinary Assistant Certification through Harper College in December of 2013. In my free time I enjoy hiking, camping, playing ice hockey, and taking my 3 dachshunds Chloe, Charlotte, and Chelsea for a run. I am currently going back to school for my Bachelor’s degree in Business Management and afterward plan on getting my Master’s degree in Marketing. My dream is to someday own an animal clinic myself. I look forward to meeting you and your furry friend soon!
Kevin, Veterinary Assistant
I joined Companion Animal Hospital in April 2018 after completing the Veterinary Assistant program at College of Lake County. I have always loved animals, and prior to this I worked at a boarding kennel/doggie day camp and also worked at a horse stable for several years. I have 3 cats at home: Tygur, Munkee, and Simon, and they keep me plenty busy. I'm looking forward to going to Tech school this fall, and learning everything I can from the rest of the terrific staff here. I can’t wait to meet you and your pets!
Hi, my name is Janice. I joined the reception team at the hospital in September of 2016. I’ve always had an interest in working in the healthcare field and to do so with animals is a bonus! I enjoy seeing the different cats and dogs here along with their owners. My favorite activities outside of work are spending time with my family, traveling, hiking, sewing, scrapbooking, and walking my German Shepherd, Louie. In my free time, I volunteer as a dog handler for several local animal rescues at their adoption events.
