Veterinarians in Kenosha: Dr. Petereit

Dr. Scott Petereit

Brief summary about yourself?

Having graduated from the University of Illinois College of Veterinary Medicine in 1991, Dr. Petereit brings over 20 years of clinical small animal medical experience to Companion Animal Hospital Kenosha. His interests include soft tissue surgery, 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, the American Veterinary Medical Association, and the Wisconsin Veterinary Medical Association.

Dr. Petereit volunteers his time to providing veterinary care to homeless pets at The Buddy Foundation, a no-kill shelter located in Arlington Heights, Illinois. When he is not helping pets he spends his time with his wife and three young children including the family dog, Tyler. In his free time, he enjoys the outdoors and loves fishing, hiking, and snowboarding.

What made you decide to become a vet?

I always loved the sciences and had raised one type of animal or another throughout my life. As a kid, I hatched and raised chickens, pigeons, and even had a pheasant as a pet. I had everything from salamanders to turtles, gerbils to 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.

What has been your most rewarding moment as a veterinarian?

No one particular moment stands out. 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.

If you weren’t a vet, what would you do?

My second career choice was to be involved in some sort of wildlife management career. Perhaps I might be in this field now.

What animal scares you more than any other?

Maggots...yuck! Unfortunately, I have seen some animals that were so debilitated that their wounds were infested with maggots. I have nightmares about maggots.

What do you consider your greatest accomplishment?

This is still a work in progress since I am still raising three children with my wife. Years from now, I hope I can look back and say that this was my greatest accomplishment.

What do you see as the greatest danger toward household pets?

Dental disease and obesity. I see both of these health issues lead to significant disease on a daily basis.

What is the most exotic animal you have treated?

A coatimundi. Basically South America's version of a raccoon. In veterinary school, I assisted with a black bear and a Siberian tiger...what an awesome animal!

What is your favorite comfort food?

I've never met a cheeseburger I did not like.

What is your biggest pet peeve?

Cigarette butts thrown from a car window.

Name 4 things people might be surprised to know about you:

I was charged by a brown bear once in Alaska

I was a college cheerleader

I am a pretty good snowboarder

I can still walk at least 20 yards in a handstand

Dr. Rau-Holl

Dr. Laura Rau-Holl

Brief summary about yourself?

Dr. Rau-Holl graduated from Michigan State University. She worked in Wisconsin for a few years, then moved to East Peoria, IL and continued to work there. She took a break from practice while her children were small, but now that they're in school, she has decided to return. Dr. Rau is a member of the American Veterinary Medical Association, and her practice interests include internal medicine and surgery. Dr. Rau enjoys spending time with her husband and children and most of their activities, such as biking, boating/watersports, and camping, center around family. On her own, Dr. Rau likes running/working out, cooking, and perhaps to a lesser degree, chauffeuring the kids to and from their activities. She volunteers as needed in their classrooms as well. They have a cat named Peter, fish, and two Bess beetles as pets.

What made you want to become a veterinarian?

I started college with the intention of becoming a registered nurse. My running coach gave me the book All Creatures Great and Small by James Herriot with the advice “consider it.”  Raised on a working dairy farm, I always had animals around me—cattle, cats, dogs, chickens, ducks—so veterinary medicine seemed like a good choice.

What has been your most rewarding moment as a veterinarian?

I cannot recall a specific moment that sets itself apart from the others. The reward as a veterinarian, to me, comes from many different facets of the job. It is rewarding at a personal level to help pets and clients through difficult situations and illnesses. It is rewarding as a doctor to solve the health puzzles that pets can present us.

If you weren’t a vet, what would you do?

I would probably be a registered nurse as I originally planned.

What animal scares you more than any other?

Horses. They are beautiful, athletic, intelligent creatures, but I do not feel I have the “horse-sense” to interpret their body language and work with them safely. Most horses have me figured out pretty quickly, though.

What do you consider your greatest accomplishment?

I have many personally significant accomplishments, but cannot rank any particular thing as a defining moment. Big things—certainly becoming a veterinarian was big, but at the end of the day, my family means the world to me.

What do you see as the greatest danger toward household pets?

Obesity. So many illnesses and quality of life issues stem from obesity. As a pet owner, I know that some days it is so easy to give out treats or food to make our pets happy, but most pets would be just as happy to be played with or taken for a walk.

What is the most exotic animal you have treated?

Hedgehog. I saw a couple of hedgehogs in my early days in practice. They are covered in small quills. They tuck their head in and curl up into a ball when they are frightened. Unless they could be coaxed out of their ball with some TLC, anesthesia was needed to even examine them.

What is your favorite comfort food?

Brownies. You can never go wrong with chocolate.

What is your biggest pet peeve?

Disorganization. I don’t mind the presence of “stuff,” as long as there is order to it.

Name 5 things people might be surprised to know about you:

I am a farm kid. I was raised on a dairy farm in Michigan.

I am the last-born of my parents’ 6 daughters. Yes, my parents were raising crops and milking cows with all girls to help them. Better still, I am 14 years younger than my youngest sister. 

I have run from Grafton, WI to Milwaukee, WI--  26.2 miles.

I am domestic. I sew, cook, and craft.

I am a pretty decent boat driver if you ski or board--fishermen probably do not see it that way. 

Dr. Juleen

Dr. Nick Juleen

Brief summary about yourself?

Dr. Juleen graduated from the University of Wisconsin School of Veterinary Medicine in 2005. He completed a 13-month emergency and critical care internship at the Animal Emergency Center (now Lakeshore Veterinary Specialists) in Glendale, Wisconsin and has practiced general medicine in Southeast Wisconsin since 2006. Dr. Juleen has a passion for veterinary dentistry and a strong interest in internal, emergency, and critical care medicine. He is a member of the American and Wisconsin Veterinary Medical Associations and the American Veterinary Dental Society. When he is not caring for pets he spends time with his wife, two young daughters, and the two family black Labradors. In his free time, you can find him in the great outdoors.

What made you want to become a vet?

When I was eight years old, I accompanied my father to the veterinarian for our family dog’s exam. After that experience, the profession “called” to me.  I was always concerned about the welfare of companion animals and took it upon myself to learn about animal husbandry as I got older. The more I learned, the more I knew this was the profession meant for me.

What has been your most rewarding moment as a veterinarian?

Being able to use the gifts given to me along with my training to return pets home happy and healthy to their loving families.

If you weren’t a vet, what would you do?

I have a passion for American history, and as such, I would be a Professor of History at a university.

What animal scares you more than any other?

While technically not an animal, parasites scare me thanks to my wife’s frequent viewing of “Monsters Inside Me” on Animal Planet!

What do you consider your greatest accomplishment?

Completing my internship in emergency and critical care medicine, and having the family I do.

What do you see as the greatest danger toward household pets?

I see two great dangers towards pets; the first is dental disease and the second is toxicities, especially rodenticide and artificial sweeteners like xylitol.

What is the most exotic animal you have treated?

During my internship, I had to do surgery on an iguana that had swallowed a penny!

What is your favorite comfort food?


What is your biggest pet peeve?

Intolerance of other's opinions and views.

Name 4 things people might be surprised to know about you:

1.)    I love to do dishes and clean!

2.)    I love to play on my Playstation 3!

3.)    Despite being in Kenosha for 10 years, I still don’t know that much about it!

4.)    Despite the winters, Wisconsin is and will always be the best place to live for me!

Dr. Kalkhof

Dr. Natasha Kalkhof

Brief summary about yourself?

Dr. Kalkhof graduated from the University of Wisconsin-Madison for her undergraduate and veterinary degrees. She spent the following year in a small animal rotating internship in Lexington, Kentucky. This involved working closely with veterinary specialists and lots of emergency experience. Dr. Kalkhof has returned to Wisconsin to be closer to family and friends and because she loves this great state! While she learned a lot from her year with specialty and emergency medicine, she’s excited to enter the world of primary practice. Her veterinary interests include preventative medicine, behavior, and ophthalmology, and she is a member of the American Veterinary Medical Association. In her spare time, Dr. Kalkhof loves traveling (abroad and domestically), spending time with family and friends, hiking, canoeing, trying new restaurants, making music, and watching Packer and Badger football games. Dr. Kalkhof has a cat named Luna (who is a beautiful princess) and a younger cat named Leroy (who is easily excitable and sometimes sweet).

What made you decide to become a vet?

I loved animals growing up, so in high school, I started working at a veterinary clinic. Not only were they helping animals, but the staff worked together so well that it was a fantastic work environment. It was a wonderful experience and I knew I would be happy as a veterinarian.

What has been your most rewarding moment as a veterinarian?

During my internship, there were multiple dogs I admitted to the hospital who had poor prognoses, either due to trauma or serious disease. Every time one was released, the tail wag as they were handed back to their owners was the most rewarding moment.

If you weren’t a vet, what would you do?

I would likely be a zookeeper, preferably at a zoo with pandas.

What animal scares you more than any other?

Spiders - they have far too many legs, even Charlotte’s Web gives me the willies!

What do you consider your greatest accomplishment?

Completing a small animal rotating internship to improve my veterinary skills and critical thinking for future patients.

What do you see as the greatest danger toward household pets?

Obesity is a complicating factor for all pets and it has become extremely common. Obesity creates additional problems as pets age and when they’re sick (such as diabetes, arthritis, hepatic lipidosis, and the list goes on).

What is the most exotic animal you have treated?

There wasn’t any treatment needed, but I helped with physical exams (including ultrasound) on multiple chimpanzees for their annual wellness exams.

What is your favorite comfort food?

Popcorn, particularly cheddar and movie theater popcorn!

What is your biggest pet peeve?

Littering, especially in nature preserves or by the lake.

  2. I lived in Ireland for 5.5 months on a pet farm and wildlife park.

Our Team


Jessica, Hospital Manager & Certified veterinary technician

I started my veterinary career here at Companion Animal Hospital in 2003 as a kennel assistant while I was in high school. I climbed the ranks to veterinary assistant in 2006 and became a certified veterinary technician in 2010. I have always had a passion for animals and medicine and am lucky enough to work in what I love. I LOVE veterinary medicine! In July of 2016, I became the hospital manager of Companion Animal Hospital Kenosha and feel very lucky and proud to be at such an amazing hospital!

When I am not at work I am a mother of twin daughters. I am also a fur-mom to a "Chi-weenie" named Jager, a Pitbull named Chili, and a cat named Link. I like to be outdoors as much as possible, go up north to our family cabins, go boating, craft with my kids, watch Packer football, play volleyball and billiards, and I love Disney movies!


Carrie, Lead Customer Service Representative

I started at Companion Animal Hospital in January of 2013 as part of the reception team, very shortly after moving into Kenosha. Before moving to Kenosha I lived in Cleveland, Ohio my entire life. I worked for many years at the largest humane society in Ohio as the Offsite Adoptions Program Coordinator, where I was in charge of all of our offsite pet store locations housing shelter cats as well as organizing all of our adoptions events. My program was responsible for 800-1000 extra adoptions for the shelter on a yearly basis.

Although it broke my heart to leave such a great program, I had a good reason for it. I moved to finally be together with my boyfriend whom I'd been dating long distance for a year. We lived briefly in Illinois before moving to Kenosha. I was happy to be adopted into the Companion family very quickly.

Aside from working the front desk at Companion Animal Hospital, I also help run a horror and pop culture convention with my boyfriend and some other great friends. When I’m not working a convention or at the hospital, I enjoy cooking (particularly coming up with exciting and unique taco recipes), the Food Network, concerts, photography, perusing bookstores and record stores, and exploring Chicago any chance I get!My four-legged family includes two cats, a Pit Bull, and a turtle.


​Sam, Certified Veterinary Technician

I grew up in Kenosha and graduated from Bradford High School in 2006. I went to Parkside after high school and graduated with a Psychology degree in 2010. I had always wanted to work with animals, so I decided to go back to school for Veterinary Technology; I had to wait a year to get in but it was worth the wait. I graduated from Madison Area Technical College with an Associate’s Degree in May 2013. Going back to school to be able to help animals every day was the best decision I have ever made! I did my internship at Companion Animal Hospital for school in the summer of 2012 and was offered a permanent full-time position when I graduated. I really enjoyed working here for my internship and was very excited to come back to work with this amazing staff. They make everyone feel like family. I really enjoy being able to help animals and to get to see awesome animals every day.

I currently live in Kenosha since graduating from Madison. I have two dogs; a Basset Hound named Murphy who likes to use his loud hound howl and a mix named Brinkley who can be very shy when meeting new people but loves giving kisses. When I am not working at the clinic, I am either at home hanging out with my dogs, up north in the summer, or watching the Packers, Brewers, or Badgers.


Ally, Customer Service Representative

I joined the Companion Animal Hospital team as a part-time receptionist in January 2016. I have always loved animals and I knew I wanted to be a part of this team after I brought my own pet to Companion and had the best experience! I have learned so much working here and it has ultimately made me a better cat mom.

I have lived in Kenosha my whole life and it is where I call home. I graduated from UW-Parkside in 2012 with two Bachelor's degrees. I married my husband, Travis, in 2013 and we adopted our first fur baby in 2014. We now have two longhaired cats, Leonardo DiCatrio, our blonde big boy, and Layla, our petite orange girl! They are both rescues and they are the light of our lives!

Outside of work I enjoy spending time with my family, playing golf, going to the casino with my husband, traveling to new places, and cuddling our two fur babies. I also really enjoy yoga, fishing, and staying active! I look forward to meeting all of you and your fur babies!


Lauren, Veterinary Assistant

I joined the team at Companion Animal Hospital in May of 2017. I work full time as a veterinary assistant; however, my goal is to become a certified veterinary technician in the near future. I learn more and more about animals daily and enjoy helping clients with their pets. I have always loved dogs and never thought I would own a cat, but working at Companion has changed my mind! In 2017 I adopted a cat named Wally, who has become a close buddy to my 70-pound Pitbull mix, Iris. My favorite breed is the French Bulldog (viva la Frenchie), and I hope to have one in my lifetime!

I was born and raised in Kenosha, WI, graduated from Harborside Academy and took some classes at UW-Parkside and Gateway Technical College. When I’m not working I enjoy fishing with my dad, hanging out with friends, and enjoying the warmer months in Wisconsin. However, during football season, I will stand in the freezing cold with my family at Lambeau to watch the Packers!

Companion Animal Hospital is a fantastic place to work and I am grateful be part of such a great team!


Mallory, Certified Veterinary Technician

I have been working at Companion Animal Hospital since April of 2018. I have always loved animals and knew that I wanted to do something with them long-term. I graduated from Gateway Technical College in 2018 with an associate degree in Veterinary Science and passed my national exam in June of 2018. I have a strong passion for animal behavior and am constantly learning more about animals every day. I love utilizing fear-free techniques when working with animals because the less stressed pets are when they see us, the healthier and happier we can keep them. I currently have two pets at home. A black lab mix named Cooper and a grey kitty named Theo, who love to play and snuggle with each other.


Laura, Customer Service Representative

I started working at Companion as a receptionist in October of 2018. I was born in Paraguay, South America, but moved to the United States in 2012 to attend university. I lived in Waukesha for 2 years finishing my associates degree in Biblical Studies, then moved to Virginia to study Linguistics and Chinese. After spending a summer in China, I decided to move to Florida, but ultimately decided I liked Wisconsin the best and moved to Racine in 2017.

I currently have two cats – a 3 year old calico named Michi and a 2 year old tabby named Nixie. When I am not working, I enjoy hanging out with friends, reading, and talking to my family who are still in Paraguay.

I look forward to meeting all your pets!


Haley, Veterinary Assistant

I grew up in Racine where I attended Case High School. After graduating in 2016 I went on to do a Dental Assisting program and became Dental Assistant with the goal of becoming a Dental Hygienist. While I enjoyed working in the dental field, deep down inside I truly knew that it wasn’t for me. Something that I have always been passionate about are animals, I had always wanted to work with animals every since I was little. When the opportunity  to work at Companion Animal Hospital arose I knew that I had to take a leap of faith and apply. I started working at Companion in November 2018 as a full time Veterinary Assistant, my goal is to become a Certified Veterinary Technician and then eventual specialize in zoo medicine.

When I am not at work I enjoy painting, doing ceramic work, being outside with my dogs and hanging out with family and friends.


Devyn, Veterinary Assistant

I am a veterinary assistant here at Companion Animal Hospital as of April 2019, and I can already say I have learned so much and genuinely enjoy my job! It has been such a rewarding experience and I consider myself lucky to continue growing here at Companion. I do plan on eventually getting my certification as a Certified Veterinary Technician one day, but for now I am enjoying learning new things everyday and getting to care for each and every one of the amazing pets we get here.

I am a Kenosha native and currently reside here, no plans as of now to leave as I do love our little town! I have a beautiful German Shepherd named Ruby and 3 sweet kitties to snuggle with. When I’m not working, I enjoy playing with my pets, spending time with close friends and family, and spending time outdoors when the weather permits!


Stephie, Veterinary Assistant

I grew up in Kenosha and graduated from Indian trail Academy in the biotechnology and environmental studies program in 2003. I attended Gateway Technical College after graduation to become a certified nursing assistant and started working at a nursing home in the Kenosha area. After working as a CNA for many years, I went back to college to be a medical assistant. I used my degree in a wide range of skill sets. In 2016, I moved down to the Jacksonville Florida area so my oldest son can attended a school for the deaf. It was their where I found my love for pit bulls and terrier mixes, it was their where I also learned what loss was. I lost my pitbull to acute kidney failure and from that day I have been working with animals since. I started working at the Jacksonville Humane Society; I started in the community animal hospital and spread my wings over to the shelter medicine side. My goal is to become a certified veterinary technician and learn more about animals.

My kids and I live in the Kenosha area. I have two boys; Paul and Aspen. When I am not working at the clinic, I am either at home hanging out with my boys or watching hockey. We are big Blackhawks fans! My kids and I spend a lot of time together and their my life line. I have one dog; a pitbull boxer mix and Parvovirus survivor named Rizzo. I look forward to meeting you and your pets!
